RJ Catalano 9a075458ad initial work for fixed types...potentially needing a constant literal type for this
notation

Rational implemented...trying to figure out exponential

fix for token bug, also quick fix for the wei and seconds

fixed problem with var...probably a conversion problem for fixed in size capabilities

adding fixed type tests

Removing bitshift and regrouping fixed type tests together

size capabilities functioning properly for fixed types

got exponents up and working with their inverse, changed a few of the tests....something is working that likely shouldn't be

slight changes to how to flip the rational negative around...still trying to figure it out

tests added

updated tests

odd differences in trying soltest from solc binary, let me know if you can replicate

test not working for odd reason

fixed test problem with fixed literals...still need a way to log this error

broken up the tests, added some, changed some things in types and began compiler work

moar tests and prepping for rebuilding much of the types.cpp file

further fixing

initial work for fixed types...potentially needing a constant literal type for this
