I changed some functions in search3x3.py and also added some new ones.
I changed checkRow, checkCol, and checkSector. These functions now use the
actual size of the puzle for n instead of using 3 for the size.

I added three functions these are action, isFilled, and is Equal.
	action: Produces all posibilities for a given sector. This function is far
			from compleate and is extreamly slow right now. I have yet to work
			out a way to speed it up, but will do so.

	isFilled: Checks a given sector and see's if all of it's cells have been
			  filled in or not.

	isEqual: Returs true it the two puzzel states are equal and false if they
			 are not.
