Voronoi Lookup

[nandantumu]

This class should take a set of (x,y,l) points, where x and y are the coordinates of a point, and the label is l. The value of l will be an integer with value from 0 to $\infty$. This set of points will be provided in the constructor. We should then be able to provide any (x,y) point, and get a label determined by the closest point, the same way that colors are assigned in a voronoi diagram.

This class should be in a file called utilities.py in the pit directory.
