Updated docs

Also fix for HashTable<>::rehash_fast not having finished implemenation...

The typedef fix is a sort of hack (like how parsing the rest of the language feels like tbh...).
I might make a def_typedef_fn to make it clearer how to define function typedefs using the upfront interface.

-* Validate a valid parameter num was provided, or code array

-
-* Begin the code entry do-while loop, make sure each entry is valid processing its type in the switc
-	def_body_code_validation_start( <name of function> )

-* Define the switch case statements between the macros.
-
-* Add the code entry, finish the closing implemenation for the do-while loop.

+# Temporary Code
+
+These are heavy macro code used throughout the library thats intended to be replaced with codegen done with the library itself.
+
+The reason for this is to minimize macro generation to only trivial cases.  
+This makes the library more verbose but makes it easier to debug which is of higher priority.
+
+Any sort of verbosity cost will be mitigated with better docs and heavy usage of pragma regions.

 # Test
 
-The following tests focus on attempting to generate some math, containers, and the memory module of zpl.
+The implementaiton here is not well organized and needs a rewrite..
 
-Not all the files are written how I would practically use the library, the containers for example would
-be better on in c++ as templates, since the templates they generate are trivial symbols to inspect or debug.
-
-An example of a non-trivial generation is a container for elements with SOA or AOS policy for layout.
-(If a unified element syntax is desired)
-
-The test is divided between two major sets of tests: Parsed and Upfront.
+I only do basic sanity and parsing tests for the most part.  
+The library is getting practical usage tests in [genc](https://github.com/Ed94/genc) and other projects.
