/**
 *  \file TransformationCartesianProductSampler.h
 *  \brief The class samples all combinations in a discrete set of
 *    transformatios.
 *    For example, for a discrete set of trasnformations:
 *    t11,t12       for particle p1
 *    t21,t22,t23   for particle p2
 *    t31,t32       for particle p3
 *    the sampling space would be:
 *    [p1^t11,p2^t21,p3^t31],[p1^t11,p2^t21,p3^t32], ... ,[p1^t12,p2^t23,p3^t31]
 *     p^t indicates the p is transforms by t
