Helper class for merging xAOD files
This is a slightly dubmed down version of ROOT's TFileMerger class in some respects, and is a bit smarter in other respects. It can be used by user code to merge xAOD files in a user friendly way from C++ code. It is also used by the xAODMerge application to do the heavy lifting during the merge.
