analyze_logicals in Axiom.py crashes the parser when dealing w/ functions

[evanmrsampson]

@Fxhnd I pulled the DL changes into the master branch so that I could take advantage of the constants distinction. However, I found that the analyze_logicals method will crash when the axiom has a function in it.

At the moment, I commented out the call to analyze_logicals and left a TODO note above it. At the moment, the editor doesn't know the difference between constants and variables until this works

Just wondering if functions will be supported soon, there are some theories I'm working with that have functions so it'd be preferable if the translation for functions is operational.

Traceback of the current error when trying to do consistency check and translation:
