@routine IOHDF5_Get_filename_ND
@author Paul Walker
@date Feb 1997
@desc Returns the filename for output
The names of all output files are stored in the filenames database.
The routine first searches in this database if there is already
registered a filename for alias. If so, this name is returned.
Otherwise it builds the filename from alias and stores it in the
database.
NOTE: Filenames are never stored if "out2D_septimefiles = true"
since they are used only once.
Generalized for Hyperslab extraction (GL)
