Determination of quadrants based on angle, coordinates and others

Another Intro To C assignment (this one tells what quadrant a point is in based on its coordinates)

Approximate Angles of any vector using it's quadrant and a radial slice index. Useful for rotation invariant indexing of a dynamic stream of x/y points. For instance, in creating pooled rotation-scale-translation invariant histograms.
