added checks on numberOfNeighbors to the various interpolate methods
minor syntax change
I forgot what KdTree.getPoints() was called; fixed that
added rhl's testTooManyNeighbors unit test to testGaussianProcess.py
fixed indentation error
added check to selfInterpolate so that it tells you if you are asking to interpolate at a point that does not exist; also expanded the new unit test so that it checks all of the interpolation routines
Fixes to displaying Images' pixels
removed tabs from testGaussianProcess.py
use assertRaises in testGaussianProcess.py
