//! Iterator to generate all permutations of a list. A functor can be specified for fast culling of entire subtrees of undesired permutations. 
/**
 *  The permuations are in lexicographic order. ie. {1,2,3} , {1,3,2} , {2,1,3} , {2,3,1} , {3,1,2} , {3,2,1}
 *  The current permutation list can be accessed with the dereference/pointer operators.
 *
 *  If a functor is provided then undesired subtrees can be culled.  The functor must provide this function:

 *  boolean operator()(const std::vector<T>& perm)
