Improve parsing error messages #9

The syntax error is not descriptive enough. There is a way to have bison generate a little more useful syntax error indicating what was expected. Need to investigate and implement better error messages.

sounds silly to have missed this, but adding '%error-verbose' to the .yy file created the desired error messages. Additionally, I added the token description to the end of the %token line for each token.
