Imported new evogpj library

Altered some of the classes from the new library to be able to accept
the classes necessary for TaxFitness. Single fitness evaluations are
currently working, but I haven't sinced up the actual GA yet as I had
with AlgorithmBase. That's next on the agenda.
Got GA working

Altered SymbRegMOO and associated classes in order to make it work with
both TaxFitness and TaxCodeFitness. Specifically, I added a main()
function inside of SymbRegMOO and changed some default parameters such
that the GA runs.
Cleaned up unnecessary items

Got rid of many fields, methods and classes that pertained to GAs not
relevant to the Tax project, as well as removed all dependencies to the
prior evo package, which I then deleted.
