Ouroboros documentation up to date

As reflected in the lib/src/Parser.* files the documentation should be accurate.
Each feature should be covered in at least a little depth.
Some work probably needs to be done on clarity and organization but the whole outline is there.
I already plan to add other features into the parser still so there are already future documentation changes planned.
Needed to delete Assembler.tex

This will need a better treatment later on once it gets integration with Galaxy
Added operators and enabled 1-tuple casting to bare type
