processPlus() Is Semi-Functional

Over the past few versions, many commented descriptions have been added
to the code

- processPlus () now recognizes homogenous color "+" 's
- rainbowColorPlus () still needs to be written
- Scoring needs to be fixed
- Consider switching Input.inputString
to
"GetKeydown ()"

* to test processPlus (), randomColor () has been reduced to one color,
turn time and game time have also been increased: Must change back for
final build
