Added a terrible version of fitness, tourney, but it contains some good
elements needed for future use. 

Added comments to these classes to see direction needed to go.

Moved population to be a static field in Evolver, instead of a local
variable, in order to access for future use in tourney.

Added a TourneyTest
Modded TourneyTest
Added Fitness List to Evolver
Fixed Fitness to have constructor that takes a list. 
Fixed Tourney to work with entire pop
Close but no cigar.

Problems with evolver.

Added generations to evolver, should remove all fields from evolver and
just have an evolve() method. And potential problem in mutation, must
investigate.

Added main method that should print initial pop and after one
generation, doesn't work.

Tourney looking good.  just removed print ln
Added a size method for gpTree
Changed Ptc2test to reflect this size change
Added a evolvertest to test initialpop
Added Treesize to evolver
Added a evolver method to evolver unfinished
All tests are working. Main method isn't yet, looks like crossover is
having problems. Need to investigate more.

Added more tests to evolverTest to test mutation and evolve methods

Added Fixed mutation to take actual evolver fields'

Changed evolver from static methods so they would be more localized.
Added more to evolve method so it now evolves by itself!
Fixed mutation field in mutation type to rid of the error message

NEED TO FINISH INPUT FITNESS AND LOOK AT MAIN
Fixed Crossover for single nodes trees

Main now evolves things. 

from the fitness list i evolved correct function.

All thats left is imput fitness from files
