Added the capability to handle compressed GDS files through the use

Browse Source 
of systems calls to "gzip" and "gunzip".  A compressed GDS file can
be made simply by doing "gds write <name>.gds.gz", and can be read
simply by doing "gds read <name>.gds.gz".  Names of compressed files
can be put in the GDS_FILE property of a cell.
