Added an additional vector<short> which keeps track of mappings from
centroid clusters to VFH signatures -- which occurs when axes can't be
disambiguated.

Also, ensured that the width and height are set properly on output when compute,
computeFeature, and computeRFAndShapeDistribution are called.

This commit includes some debugging output which will be removed
in the next commit.
