Dot product of 3d vector.

The dot product essentially "multiplies" 2 vectors. If the 2 vectors are perfectly aligned, then it makes sense that multiplying them would mean just multiplying their magnitudes. It's when the angle between the vectors is not 0, that things get tricky. So what we do, is we project a vector onto the other.
