- Made a better global allocator for the process. - Some small fixes to gen.hpp, removed clear_code_memory as I'm designing this library to for now never free any memory. - Fixes to memory usage for cached strings - Added missing verification for attributes in some upfront constructors. Added attribute param for def_type procedure. - Started to use internal and global keywords in gen.cpp for associated definitions - Progress toward getting the parsing constructors to support operator definitions. - There was an *attempt* to get parse_type to support parsing function types. Its not tested yet.... - Its not an nice setup, there is no validation of parameters, problably will add that in the future.
