Initial creation
It seems that SinglePointCrossover works and has a working test!
Test for SinglePointCrossover
TwoPointCrossover and its test should be good to go!
Two point crossover and its test should be good to go
All the crossovers should be done
COMMENTED A LINE OUT
Groovified code and improved tests.
Removed extraneous println in SinglePointCrossover
Added a mirror image test in UniformCrossoverTest
Added the mirror test to SinglePoint and TwoPoint tests
Added toString methods which return the initials of the Operator
Fixed two bugs in the tests that prevented them from running. The new
"mirror image" test was clearly written once and copy-pasted into the
other two operators but never run. A name needed to be changed to get
that to run.
