NOTES:
1. This implemention borrowed some basic framework from Rabner s original EMD code.
2. Histogram matrices are assumed to be arranged in the "matlab" style, i.e, the [i,j,k]-th element is
located in the position
i*(n2*n3)+ j*(n3)+ k
3. The example usage of the code is demonstrated in
emdL1_test.cpp
4. This is version 2. It has been tested using VC++ 6.0, and VC 2005 (professional version).
