NAME
    	compress - does file compression within a network

SUMMARY

    	Name	    compress
    	Type	    input
    	Inputs	    string
    	    	    field 
    	Outputs	    none

DESCRIPTION

The compress/uncompress module pair is designed to allow datasets or
images or other files to be stored and kept in compressed format, but
still be read into an AVS network.  The compress module is designed to
be used after a file has been uncompressed and read into the network
via "read field" or the like.  As such, it requires both a changed
filename (indicating that a new file is being read into the network)
and a new field (indicating that the read field module has finished
reading the data and has begun to pass it to the network).  Since this
module takes a generic field as input, it also works with images and
volumes, but not UCD's or Geometries, as distributed.  It can easily
be modified to accept any other type of input, however.  As with
standard unix compress, there must be enough room on the disk to
create the compressed file.  Presumably, if this module is used in
conjunction with the uncompress module, this will be true.

    	Filename of file to be compressed (string)
