-changed back 'hello' (in the tester class)

-finished body and eyes classes
	-instead of making constants for blueEyesChance, brownEyesChance, etc.
	 I made it so the chance of getting that phenotype is the same as the 	
	 length of the DNA list for that gene. If you guys want it to be the 	
	 old way (like it is in the hair class) i can change it this way is 	 	
	 just a lot less code.  
-fixed some documentation in hair
