Well, the direct solution would be to determine whether or not MOAB used 
the ReadCGM class to read the file.  But asking about the file type is 
equally indirect, as CGM can read a variety of file formats as well.  If 
we do want to proved the string name of the reader, then I think the way 
to do this is to use a file set.  The MOAB load_file function allows an 
optional EntitySet handle to be passed.  If that handle is provided, the 
contents of the file will be added to the set.  MOAB should hang 
pertinent data in tags on that set (file name, file reader name/file 
type, etc.)
