Added parser files in 01_parser. For now, all the parser
does is output the tokens in the order it got them.
A lot of work done. I messed something up, and I lost a lot of
work on lexer.cpp, so I am committing now to save everything.
Wrote a function to process numbers in lexer.cpp.
Added keywords to kate xml file.
Initial work to get identifiers and keywords working.
Last commit for the night. Did more work on keywords. I am
hoping to do debugging on Monday.
