trait CharBasedParser[J] extends Parser[J]
Trait used when the data to be parsed is in UTF-16.
This parser provides parseString(). Like ByteBasedParser it has fast/slow paths for string parsing depending on whether any escapes are present.
It is simpler than ByteBasedParser.

The reset() method is used to signal that we're working from the given position, and any previous data can be released.
The reset() method is used to signal that we're working from the given position, and any previous data can be released. Some parsers (e.g. StringParser) will ignore release, while others (e.g. PathParser) will need to use this information to release and allocate different areas.

Parse the JSON document into a single JSON value.
The parser considers documents like '333', 'true', and '"foo"' to be valid, as well as more traditional documents like [1,2,3,4,5]. However, multiple top-level objects are not allowed.

Parse the given number, and add it to the given context.
We don't actually instantiate a number here, but rather pass the string of for future use. Facades can choose to be lazy and just store the string. This ends up being way faster and has the nice side-effect that we know exactly how the user represented the number.

parseNumSlow(i: Int, facade: Visitor[_, J]): (J, Int)
Parse the given number, and add it to the given context.
Parse the given number, and add it to the given context.
This method is a bit slower than parseNum() because it has to be sure it doesn't run off the end of the input.
Normally (when operating in rparse in the context of an outer array or object) we don't need to worry about this and can just grab characters, because if we run out of characters that would indicate bad input. This is for cases where the number could possibly be followed by a valid EOF.
This method has all the same caveats as the previous method.

rparse(state: Int, j: Int, stack: List[ObjArrVisitor[_, J]]): (J, Int)
Tail-recursive parsing method to do the bulk of JSON parsing.
Tail-recursive parsing method to do the bulk of JSON parsing.
This single method manages parser states, data, etc. Except for parsing non-recursive values (like strings, numbers, and constants) all important work happens in this loop (or in methods it calls, like reset()).
Currently the code is optimized to make use of switch statements. Future work should consider whether this is better or worse than manually constructed if/else statements or something else. Also, it may be possible to reorder some cases for speed improvements.
