Parser constructor passes all current tests...

Pretty much have a working library now... Albiet with problably quite a few hidden bugs in parsing.

Next steps are to start converting library to use its own Arena, Pool, Array, HashTable types. And either work on zpl dependency gutting or making a more robust set of tests.

 # TODO
 
-* May be in need of a better name, I found a few repos with this same one...
+* Implement a context stack for the parsing, allows for accurate scope validation for the AST types.
-* Make a test suite made up of collections based of the ZPL library templated colllection macros and the memory module.
+* Make a test suite thats covers some base cases and zpl containers (+ anything else suitable)
+* Finish support for module specifiers and standard/platform attributes.
 * Remove full ZPL dependency, move into Bloat header/source only what is used.
 * Generate a single-header library.
 * Actually get to version 1.
