Refactor 4 done

Smaller refactors made I changed the name of t to _type and ct to _componentType as I missed them from naming refactor.

Next I also fixed the warning from Class _class and any other use of Class. Instead using Class <?> since it can be any type even Class<?>[]

Lastly, I quickly changed the for loop in the code from standard for(int i=0; i<length; i++) style to for (Field field: _fields)
