Added a section for syntax along with some expressions that we need. Need to get these nailed down so we can really start mashing out a compiler.
Notes on symbolic enums added.
More notes on boolean values. Decided to make them capitalized for consistency with the symbolic enums -- essentially a boolean type is a predefined symbolic enum.
Slight modification to byte.
Moved boolean before input / output. Seems to make more sense as inputs and outputs are boolean values.
Added a declaration for the boolean identifier.
Using <variable> not <variable_identifier>
Changing to EBNF.
expression, not <expression>
More stuff added to variables.

Changed simple expressions to EBNF. This is still not 100% finished.
Changed symbolic enum to EBNF.
Added missing comma for symbolic enum EBNF.
