Did a lot of work to get keywords and identifiers working.
They're not perfect, but the output shows that it's close.
Finishing the lexer. This code has only been tested on the
main.yr file in the src folder. Further tests will be used
to prove that the lexer is flawless.
Added a tests folder with a file to help test the lexer.
Also added a README to that folder.
Did extensive testing on the lexer. Now it passes the test
file without problem. There are probably still bugs (and
missing features), but for now, it runs perfectly.
One stage down, many more to go.
Made changes to the SYNTAX file and added TODO's to
both TODO files.
