Fixed bug(s) in evalBin
Equivalence class tests also use the QuickCheck module now.
Added a "run mode" to Main.hs (Debug / Release). In case of Debug, the results of QuickCheck and Z3 will be compared (and an error will be thrown if they have different results). In Release mode, this doesn’t happen.

Refactored Test code to work with Z3 code.
Integrated Test module in Server code.
