Added several useful util functions to create features. This functions are not limited to the simple 2D case.

Example dense inference

adding Python example for dense inference adapted from the original C++ example (http://www.philkr.net/home/densecrf)

A couple README fixes for generic addPairwiseEnergy

Fixed transposed pairwise feature size in README, and noted that feature dimensionality is not necessarily equal to number of labels.
