Description of file structure and output files

There are three directories:
    dump/   - restart files are stored here
    out/  - output is stored here
    matrix/  - matrix data for radial matrix solve is stored here
All three directories may be cleared for a clean start (iget=0).

To clean up the GEM directory,  run the executable: 
clean
  rm -f gem  *.o matrix/* out/* dump/* plot yyre* flux* indicator run.out freq *.ps  *.e*

Note that the IDL scripts (*.pro) are in the GEM directory at this time.
