/**
* Creates a `lodash` object which wraps `value` to enable implicit method
* chain sequences. Methods that operate on and return arrays, collections,
* and functions can be chained together. Methods that retrieve a single value
* or may return a primitive value will automatically end the chain sequence
* and return the unwrapped value. Otherwise, the value must be unwrapped
* with `_#value`.
*
* Explicit chain sequences, which must be unwrapped with `_#value`, may be
* enabled using `_.chain`.
*
* The execution of chained methods is lazy, that is, it's deferred until
* `_#value` is implicitly or explicitly called.
*
* Lazy evaluation allows several methods to support shortcut fusion.
* Shortcut fusion is an optimization to merge iteratee calls; this avoids
* the creation of intermediate arrays and can greatly reduce the number of
* iteratee executions. Sections of a chain sequence qualify for shortcut
* fusion if the section is applied to an array and iteratees accept only
* one argument. The heuristic for whether a section qualifies for shortcut
* fusion is subject to change.
*
* Chaining is supported in custom builds as long as the `_#value` method is
* directly or indirectly included in the build.
*
* In addition to lodash methods, wrappers have `Array` and `String` methods.
*
* The wrapper `Array` methods are:
* `concat`, `join`, `pop`, `push`, `shift`, `sort`, `splice`, and `unshift`
*
* The wrapper `String` methods are:
* `replace` and `split`
*
* The wrapper methods that support shortcut fusion are:
* `at`, `compact`, `drop`, `dropRight`, `dropWhile`, `filter`, `find`,
* `findLast`, `head`, `initial`, `last`, `map`, `reject`, `reverse`, `slice`,
* `tail`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, and `toArray`
*
* The chainable wrapper methods are:
* `after`, `ary`, `assign`, `assignIn`, `assignInWith`, `assignWith`, `at`,
* `before`, `bind`, `bindAll`, `bindKey`, `castArray`, `chain`, `chunk`,
* `commit`, `compact`, `concat`, `conforms`, `constant`, `countBy`, `create`,
* `curry`, `debounce`, `defaults`, `defaultsDeep`, `defer`, `delay`,

/**
* Creates a throttled function that only invokes `func` at most once per

* method to cancel delayed `func` invocations and a `flush` method to
* immediately invoke them. Provide `options` to indicate whether `func`
* should be invoked on the leading and/or trailing edge of the `wait`
* timeout. The `func` is invoked with the last arguments provided to the
* throttled function. Subsequent calls to the throttled function return the
* result of the last `func` invocation.
*
* **Note:** If `leading` and `trailing` options are `true`, `func` is
* invoked on the trailing edge of the timeout only if the throttled function
* is invoked more than once during the `wait` timeout.
*
* If `wait` is `0` and `leading` is `false`, `func` invocation is deferred
* until to the next tick, similar to `setTimeout` with a timeout of `0`.

// a transform stream is a readable/writable stream where you do
// something with the data. Sometimes it's called a "filter",
// but that's not a great name for it, since that implies a thing where
// some bits pass through, and others are simply ignored. (That would
// be a valid example of a transform, of course.)
//
// While the output is causally related to the input, it's not a
// necessarily symmetric or synchronous transformation. For example,
// a zlib stream might take multiple plain-text writes(), and then
// emit a single compressed chunk some time in the future.
//
// Here's how this works:
//
// The Transform stream has all the aspects of the readable and writable
// stream classes. When you write(chunk), that calls _write(chunk,cb)
// internally, and returns false if there's a lot of pending writes
// buffered up. When you call read(), that calls _read(n) until
// there's enough pending readable data buffered up.
//
// In a transform stream, the written data is placed in a buffer. When
// _read(n) is called, it transforms the queued up data, calling the
// buffered _write cb's as it consumes chunks. If consuming a single
// written chunk would result in multiple output chunks, then the first
// outputted bit calls the readcb, and subsequent chunks just go into
// the read buffer, and will cause it to emit 'readable' if necessary.
//
// This way, back-pressure is actually determined by the reading side,
// since _read has to be called to start processing a new chunk. However,
// a pathological inflate type of transform can cause excessive buffering
// here. For example, imagine a stream where every byte of input is
// interpreted as an integer from 0-255, and then results in that many
// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in
// 1kb of data being output. In this case, you could write a very small
// amount of input, and end up with a very large amount of output. In
// such a pathological inflating mechanism, there'd be no way to tell
// the system to stop doing the transform. A single 4MB write could
// cause the system to run out of memory.
//
// However, even in such a pathological case, only a single written chunk
// would be consumed, and then the rest would wait (un-transformed) until
// the results of the previous transformed chunk were consumed.

It is also called to create a window for dictionary data when a dictionary

Providing output buffers larger than 32K to inflate() should provide a speed
advantage, since only the last 32K of output is copied to the sliding window

Decode literal, length, and distance codes and write out the resulting

LEN -- ran out of enough output space or enough available input
TYPE -- reached end of block code, inflate() to interpret next block
BAD -- error in block data
Notes:
- The maximum input bits used by a length/distance pair is 15 bits for the
length code, 5 bits for the length extra, 15 bits for the distance code,
and 13 bits for the distance extra. This totals 48 bits, or six bytes.
Therefore if strm.avail_in >= 6, then there is enough input to avoid
checking for available input while decoding.
- The maximum bytes that a single length/distance pair can output is 258
bytes, which is the maximum length that can be coded. inflate_fast()
requires strm.avail_out >= 258 for each loop to avoid checking for
output space.

Process a set of code lengths to create a canonical Huffman code. The
code lengths are lens[0..codes-1]. Each length corresponds to the
symbols 0..codes-1. The Huffman code is generated by first sorting the
symbols by length from short to long, and retaining the symbol order
for codes with equal lengths. Then the code starts with all zero bits
for the first code of the shortest length, and the codes are integer
increments for the same length, and zeros are appended as the length
increases. For the deflate format, these bits are stored backwards
from their more natural integer increment ordering, and so when the
decoding tables are built in the large loop below, the integer codes
are incremented backwards.
This routine assumes, but does not check, that all of the entries in
lens[] are in the range 0..MAXBITS. The caller must assure this.
1..MAXBITS is interpreted as that code length. zero means that that
symbol does not occur in this code.
The codes are sorted by computing a count of codes for each length,
creating from that a table of starting indices for each length in the
sorted table, and then entering the symbols in order in the sorted
table. The sorted table is work[], with that space being provided by
the caller.
The length counts are used for other purposes as well, i.e. finding
the minimum and maximum length codes, determining if there are any
codes at all, checking for a valid set of lengths, and looking ahead
at length counts to determine sub-table sizes when building the
decoding tables.

Create and fill in decoding tables. In this loop, the table being
filled is at next and has curr index bits. The code being used is huff
with length len. That code is converted to an index by dropping drop
bits off of the bottom. For codes where len is less than drop + curr,
those top drop + curr - len bits are incremented through all values to
fill the table with replicated entries.
root is the number of index bits for the root table. When len exceeds
root, sub-tables are created pointed to by the root entry with an index
of the low root bits of huff. This is saved in low to check for when a
new sub-table should be started. drop is zero when the root table is
being filled, and drop is root when sub-tables are being filled.
When a new sub-table is needed, it is necessary to look ahead in the
code lengths to determine what size sub-table is needed. The length
counts are used for this, and so count[] is decremented as codes are
entered in the tables.
used keeps track of how many table entries have been allocated from the
provided *table space. It is checked for LENS and DIST tables against
the constants ENOUGH_LENS and ENOUGH_DISTS to guard against changes in
the initial root table size constants. See the comments in inftrees.h
for more information.
sym increments through all symbols, and the loop terminates when
all codes of length max, i.e. all codes, have been processed. This
routine permits incomplete codes, so another loop after this one fills
in the rest of the decoding tables with invalid code markers.

// - If it *is* a mark ligature, we don't allocate a new ligature id, and leave

// a base ligature in GPOS. Eg. if the sequence is: LAM,LAM,SHADDA,FATHA,HEH,
// and LAM,LAM,HEH for a ligature, they will leave SHADDA and FATHA with a
// ligature id and component value of 2. Then if SHADDA,FATHA form a ligature
// later, we don't want them to lose their ligature id/component, otherwise
// GPOS will fail to correctly position the mark ligature on top of the
// LAM,LAM,HEH ligature. See https://bugzilla.gnome.org/show_bug.cgi?id=676343
//
// - If a ligature is formed of components that some of which are also ligatures
// themselves, and those ligature components had marks attached to *their*
// components, we have to attach the marks to the new ligature component
// positions! Now *that*'s tricky! And these marks may be following the
// last component of the whole sequence, so we should loop forward looking
// for them and update them.
//
// Eg. the sequence is LAM,LAM,SHADDA,FATHA,HEH, and the font first forms a
// 'calt' ligature of LAM,HEH, leaving the SHADDA and FATHA with a ligature
// id and component == 1. Now, during 'liga', the LAM and the LAM-HEH ligature
// form a LAM-LAM-HEH ligature. We need to reassign the SHADDA and FATHA to
// the new ligature with a component value of 2.

// Has several variations in 1978, 1983, 1990 and 1997.
// JIS X 0212 - Supplementary plane of 6067 chars in 94x94 plane. 1990. Effectively dead.
// JIS X 0213 - Extension and modern replacement of 0208 and 0212. Total chars: 11233.
// 2 planes, first is superset of 0208, second - revised 0212.
// Introduced in 2000, revised 2004. Some characters are in Unicode Plane 2 (0x2xxxx)
// Byte encodings are:
// * Shift_JIS: Compatible with 0201, uses not defined chars in top half as lead bytes for double-byte
// encoding of 0208. Lead byte ranges: 0x81-0x9F, 0xE0-0xEF; Trail byte ranges: 0x40-0x7E, 0x80-0x9E, 0x9F-0xFC.
// Windows CP932 is a superset of Shift_JIS. Some companies added more chars, notably KDDI.
// * EUC-JP: Up to 3 bytes per character. Used mostly on *nixes.
// 0x00-0x7F - lower part of 0201
// 0x8E, 0xA1-0xDF - upper part of 0201
// (0xA1-0xFE)x2 - 0208 plane (94x94).
// 0x8F, (0xA1-0xFE)x2 - 0212 plane (94x94).
// * JIS X 208: 7-bit, direct encoding of 0208. Byte ranges: 0x21-0x7E (94 values). Uncommon.
// Used as-is in ISO2022 family.
// * ISO2022-JP: Stateful encoding, with escape sequences to switch between ASCII,
// 0201-1976 Roman, 0208-1978, 0208-1983.
// * ISO2022-JP-1: Adds esc seq for 0212-1990.
// * ISO2022-JP-2: Adds esc seq for GB2313-1980, KSX1001-1992, ISO8859-1, ISO8859-7.
// * ISO2022-JP-3: Adds esc seq for 0201-1976 Kana set, 0213-2000 Planes 1, 2.
// * ISO2022-JP-2004: Adds 0213-2004 Plane 1.
//
// After JIS X 0213 appeared, Shift_JIS-2004, EUC-JISX0213 and ISO2022-JP-2004 followed, with just changing the planes.

Lookup table to map the previous two bytes to a context id.
There are four different context modeling modes defined here:
CONTEXT_LSB6: context id is the least significant 6 bits of the last byte,
CONTEXT_MSB6: context id is the most significant 6 bits of the last byte,
CONTEXT_UTF8: second-order context model tuned for UTF8-encoded text,
CONTEXT_SIGNED: second-order context model tuned for signed integers.
The context id for the UTF8 context model is calculated as follows. If p1
and p2 are the previous two bytes, we calcualte the context as
context = kContextLookup[p1] | kContextLookup[p2 + 256].
If the previous two bytes are ASCII characters (i.e. < 128), this will be
equivalent to
context = 4 * context1(p1) + context2(p2),
where context1 is based on the previous byte in the following way:
0 : non-ASCII control
1 : \t, \n, \r
2 : space
3 : other punctuation
4 : " '
5 : %
6 : ( < [ {
7 : ) > ] }
8 : , ; :
9 : .
10 : =
11 : number
12 : upper-case vowel
13 : upper-case consonant
14 : lower-case vowel
15 : lower-case consonant
and context2 is based on the second last byte:
0 : control, space
1 : punctuation
2 : upper-case letter, number
3 : lower-case letter
If the last byte is ASCII, and the second last byte is not (in a valid UTF8
stream it will be a continuation byte, value between 128 and 191), the
context is the same as if the second last byte was an ASCII control or space.
If the last byte is a UTF8 lead byte (value >= 192), then the next byte will
be a continuation byte and the context id is 2 or 3 depending on the LSB of
the last byte and to a lesser extent on the second last byte if it is ASCII.
If the last byte is a UTF8 continuation byte, the second last byte can be:
- continuation byte: the next byte is probably ASCII or lead byte (assuming
4-byte UTF8 characters are rare) and the context id is 0 or 1.
- lead byte (192 - 207): next byte is ASCII or lead byte, context is 0 or 1
- lead byte (208 - 255): next byte is continuation byte, context is 2 or 3
The possible value combinations of the previous two bytes, the range of
context ids and the type of the next byte is summarized in the table below:
|--------\-----------------------------------------------------------------|
| \ Last byte |
| Second \---------------------------------------------------------------|
| last byte \ ASCII | cont. byte | lead byte |
| \ (0-127) | (128-191) | (192-) |
|=============|===================|=====================|==================|
| ASCII | next: ASCII/lead | not valid | next: cont. |
| (0-127) | context: 4 - 63 | | context: 2 - 3 |
|-------------|-------------------|---------------------|------------------|
| cont. byte | next: ASCII/lead | next: ASCII/lead | next: cont. |
| (128-191) | context: 4 - 63 | context: 0 - 1 | context: 2 - 3 |
|-------------|-------------------|---------------------|------------------|
| lead byte | not valid | next: ASCII/lead | not valid |
| (192-207) | | context: 0 - 1 | |
|-------------|-------------------|---------------------|------------------|
| lead byte | not valid | next: cont. | not valid |
| (208-) | | context: 2 - 3 | |
|-------------|-------------------|---------------------|------------------|
The context id for the signed context mode is calculated as:
context = (kContextLookup[512 + p1] << 3) | kContextLookup[512 + p2].
For any context modeling modes, the context ids can be calculated by |-ing
together two lookups from one table using context model dependent offsets:
context = kContextLookup[offset1 + p1] | kContextLookup[offset2 + p2].
where offset1 and offset2 are dependent on the context mode.
