The format for a multigrid file resembles the single Gridstat data file. The lines of the single files are simply placed below each other without any blank lines in between. The function reads in a file and tests if it is a multigrid file. Multigrid files are separated into single Gridstat temp files. The file path for the temp files is returned. If the file is a single grid files the path is left unaltered.
