Class BGC.DataStructures.Generic.Node< T >: : adding some functions to make this easier to use would be ideal

BGC::DataStructures::Generic::Node Global BGC.DataStructures.Generic.Node< T >.Node (T value, List< Node< T >> children) : Do we really want the node taking ownership of the passed-in list?

BGC::Mathematics::Combinatorics Global BGC.Mathematics.Combinatorics.AllCombinationsGenerator (int[] indexes, int outputSize) : needs to generate one at a time rather than use the list method that is provided arrays.
