Returns the distance between 2 2D or 3D points

These functions use pythagoras' theorem to find the distance between 2 points by finding the square root of the x-distance squared plus by the y-distance squared and if 3D then the z-distance squared as well. It doesn't matter if X1-X2 is negative because you square it.
