/*!
* Merges two Nif trees into one. For standard Nif files, any blocks with the same name are merged. For Kf files, blocks are attatched to those that match the name specified in the KF root block. The data stored in a NIF file varies from version to version. Usually you are safe with the default option (the highest availiable version) but you may need to use an earlier version if you need to clone an obsolete piece of information.
