Added in list support and quoted expressions. Also added an eq and in function. Had to do some major reworking to get this done. Also made some improvements in terms of setParseAction. setParseAction now pushes ints and floats unto the stack so we don't have to guess and do long or float conversions. The code looks uglier now because I couldn't find a nice way to pass around the stack. It works for now and so say the tests soo.... until we come around again to make it pretty.
