// LatticeMaker is a tool to simplify Lattice building for an         //
// arbitrary n:m relationship.  The user provides 2 ROOT collections  //
// and an association function and the LatticeMaker build and returns //
// a Lattice.                                                         //
//                                                                    //
// Caution: the LatticeMakeer is not particularly efficient; it loops //
//          over all n*m combinations to fill out the Lattice.  Use   //
//          LatticeBuilder for a simple 1:n Lattice.                  //
//                                                                    //
