expose a function for determining top level type of json

[Former user]

For example, you have a function for parsing a json array into tokens, or parsing a json object into tokens, but (so far as I can tell) no way to determine if the input string is an array or an object. Is there one I missed? For now I made a copy of advance past whitespace which provides the type.

I've been meaning to add such a thing. Here is a start. Note that it required a new public "JSON Value type" enum.
