class TFileMergeInfo


TFileMergeInfo

This class helps passing information from the TFileMerger to
the objects being merged.

 It provides access to the output directory pointer (fOutputDirectory)
 to whether or not this is the first time Merge is being called in the
serie (for example for TTree, the first time we also need to Clone
the object on which Merge is called), and provides for a User Data
object to be passed along to each of the calls to Merge.
The fUserData object is owned by the TFileMergeInfo and will be
deleted when the TFileMerger moves on to the next set of objects.
