+ * CharStrings are encoded following the the CharString Encoding sequence

+ * The value in a byte indicates a command, a number, or subsequent bytes
+ * that are to be interpreted in a special way.
+ *
+ * CharString Number Encoding:
+ * A CharString byte containing the values from 32 through 255 inclusive
+ * indicate an integer. These values are decoded in four ranges.
+ *
+ * 1. A CharString byte containing a value, v, between 32 and 246 inclusive,
+ * indicate the integer v - 139. Thus, the integer values from -107 through
+ * 107 inclusive may be encoded in single byte.
+ *
+ * 2. A CharString byte containing a value, v, between 247 and 250 inclusive,
+ * indicates an integer involving the next byte, w, according to the formula:
+ * [(v - 247) x 256] + w + 108
+ *
+ * 3. A CharString byte containing a value, v, between 251 and 254 inclusive,
+ * indicates an integer involving the next byte, w, according to the formula:
+ * -[(v - 251) * 256] - w - 108
+ *
+ * 4. A CharString containing the value 255 indicates that the next 4 bytes
+ * are a two complement signed integer. The first of these bytes contains the
+ * highest order bits, the second byte contains the next higher order bits
+ * and the fourth byte contain the lowest order bits.
+ *
+ *
+ * CharString Command Encoding:
+ * CharStrings commands are encoded in 1 or 2 bytes.
+ *
+ * Single byte commands are encoded in 1 byte that contains a value between
+ * 0 and 31 inclusive.
+ * If a command byte contains the value 12, then the value in the next byte
+ * indicates a command. This "escape" mechanism allows many extra commands
+ * to be encoded and this encoding technique helps to minimize the length of
+ * the charStrings.

+// 4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
+// 5. Avoid exposing implementation details on user objects (eg. expando properties)
+// 6. Provide a clear path for implementation upgrade to WeakMap in 2014

+ * This file contains the parser used to parse out a TeX expression from the

+ * well.
+ *
+ * The strategy of this parser is as such:
+ *
+ * The main functions (the `.parse...` ones) take a position in the current
+ * parse string to parse tokens from. The lexer (found in Lexer.js, stored at
+ * this.lexer) also supports pulling out tokens at arbitrary places. When
+ * individual tokens are needed at a position, the lexer is called to pull out a
+ * token, which is then used.
+ *
+ * The parser has a property called "mode" indicating the mode that
+ * the parser is currently in. Currently it has to be one of "math" or
+ * "text", which denotes whether the current environment is a math-y
+ * one or a text-y one (e.g. inside \text). Currently, this serves to
+ * limit the functions which can be used in text mode.
+ *
+ * The main functions then return an object which contains the useful data that
+ * was parsed at its given point, and a new position at the end of the parsed
+ * data. The main functions can call each other and continue the parsing by
+ * using the returned position as a new starting point.
+ *
+ * There are also extra `.handle...` functions, which pull out some reused
+ * functionality into self-contained functions.
+ *
+ * The earlier functions return ParseNodes.
+ * The later functions (which are called deeper in the parse) sometimes return
+ * ParseFuncOrArgument, which contain a ParseNode as well as some data about
+ * whether the parsed object is a function which is missing some arguments, or a
+ * standalone object which can be used as an argument to another function.

+/* This file contains a list of functions that we parse, identified by
+ * the calls to defineFunction.
+ *
+ * The first argument to defineFunction is a single name or a list of names.
+ * All functions named in such a list will share a single implementation.
+ *
+ * Each declared function can have associated properties, which
+ * include the following:
+ *
+ * - numArgs: The number of arguments the function takes.
+ * If this is the only property, it can be passed as a number
+ * instead of an element of a properties object.
+ * - argTypes: (optional) An array corresponding to each argument of the
+ * function, giving the type of argument that should be parsed. Its
+ * length should be equal to `numArgs + numOptionalArgs`. Valid
+ * types:
+ * - "size": A size-like thing, such as "1em" or "5ex"
+ * - "color": An html color, like "#abc" or "blue"
+ * - "original": The same type as the environment that the
+ * function being parsed is in (e.g. used for the
+ * bodies of functions like \color where the first
+ * argument is special and the second argument is
+ * parsed normally)
+ * Other possible types (probably shouldn't be used)
+ * - "text": Text-like (e.g. \text)
+ * - "math": Normal math
+ * If undefined, this will be treated as an appropriate length
+ * array of "original" strings
+ * - greediness: (optional) The greediness of the function to use ungrouped
+ * arguments.
+ *
+ * E.g. if you have an expression
+ * \sqrt \frac 1 2
+ * since \frac has greediness=2 vs \sqrt's greediness=1, \frac
+ * will use the two arguments '1' and '2' as its two arguments,
+ * then that whole function will be used as the argument to
+ * \sqrt. On the other hand, the expressions
+ * \frac \frac 1 2 3
+ * and
+ * \frac \sqrt 1 2
+ * will fail because \frac and \frac have equal greediness
+ * and \sqrt has a lower greediness than \frac respectively. To
+ * make these parse, we would have to change them to:
+ * \frac {\frac 1 2} 3
+ * and
+ * \frac {\sqrt 1} 2
+ *
+ * The default value is `1`
+ * - allowedInText: (optional) Whether or not the function is allowed inside
+ * text mode (default false)
+ * - numOptionalArgs: (optional) The number of optional arguments the function
+ * should parse. If the optional arguments aren't found,
+ * `null` will be passed to the handler in their place.
+ * (default 0)
+ * - infix: (optional) Must be true if the function is an infix operator.
+ *
+ * The last argument is that implementation, the handler for the function(s).
+ * It is called to handle these functions and their arguments.
+ * It receives two arguments:
+ * - context contains information and references provided by the parser
+ * - args is an array of arguments obtained from TeX input
+ * The context contains the following properties:
+ * - funcName: the text (i.e. name) of the function, including \
+ * - parser: the parser object
+ * - lexer: the lexer object
+ * - positions: the positions in the overall string of the function
+ * and the arguments.
+ * The latter three should only be used to produce error messages.
+ *
+ * The function should return an object with the following keys:
+ * - type: The type of element that this is. This is then used in
+ * buildHTML/buildMathML to determine which function
+ * should be called to build this node into a DOM node
+ * Any other data can be added to the object, which will be passed
+ * in to the function in buildHTML/buildMathML as `group.value`.
