* Initial parser rewrite effort Lexer and Token cleanup, Parser started over * Greatly improved parser syntax * Reimplemented using declarations and variable placement parsing * Added back unions and structs * Added enums as well as mathematical expressions (+, -, *, /, <<, >>, &, |, ^) * Code style improvement * Implemented arrays and fixed memory issues * Fixed more memory issues in parser, reimplemented validator, evaluator and patterns * Fixed builtin types, arrays and reimplemented strings * Improved error messages * Made character a distinct type, used for chars and strings * Implemented padding, fixed arrays * Added bitfields * Added rvalue parsing, no evaluating yet * Added .idea folder to gitignore * Fixed build on MacOS * Added custom implementation of integral concept if not available * Rebased onto master * Fixed array variable decl crash * Added rvalues and dot syntax * Lower case all pattern language error messages * Fixed typo in variable name * Fixed bug where preprocessor would not ignore commented out directives * Reimplemented pointers * Fixed rebase issues
