/**
* The scss compiler and parser.
*
* Converting SCSS to CSS is a three stage process. The incoming file is
parsed
* by `Parser` into a syntax tree, then it is compiled into another tree
* representing the CSS structure by `Compiler`. The CSS tree is fed into a
* formatter, like `Formatter` which then outputs CSS as a string.
*
* During the first compile, all values are *reduced*, which means that
their
* types are brought to the lowest form before being dump as strings. This
* handles math equations, variable dereferences, and the like.
*
* The `compile` function of `Compiler` is the entry point.
*
* In summary:
*
* The `Compiler` class creates an instance of the parser, feeds it SCSS
code,
* then transforms the resulting tree to a CSS tree. This class also holds
the
* evaluation context, such as all available mixins and variables at any
given
* time.
*
* The `Parser` class is only concerned with parsing its input.
*
* The `Formatter` takes a CSS tree, and dumps it to a formatted string,
* handling things like indentation.

* Parse a single chunk off the head of the buffer and append it to the

* parsed.
*
* This parser is most similar to a recursive descent parser. Single
* functions represent discrete grammatical rules for the language, and
* they are able to capture the text that represents those rules.
*
* Consider the function Compiler::keyword(). (All parse functions are
* structured the same.)
*
* The function takes a single reference argument. When calling the
* function it will attempt to match a keyword on the head of the
buffer.
* If it is successful, it will place the keyword in the referenced
* argument, advance the position in the buffer, and return true. If it
* fails then it won't advance the buffer and it will return
false.
*
* All of these parse functions are powered by Compiler::match(), which
behaves
* the same way, but takes a literal regular expression. Sometimes it
is
* more convenient to use match instead of creating a new function.
*
* Because of the format of the functions, to parse an entire string of
* grammatical rules, you can chain them together using &&.
*
* But, if some of the rules in the chain succeed before one fails,
then
* the buffer position will be left at an invalid state. In order to
* avoid this, Compiler::seek() is used to remember and set buffer
positions.
*
* Before parsing a chain, use $s = $this->count to remember the
current
* position into $s. Then if a chain fails, use $this->seek($s) to
* go back where we started.
