Rachel setup file

One setup file must be created before running Rachel.  This is the <tt>.rachel_setup</tt> file, which should be placed either in the working directory or in the home directory.  The contents of the file are as follows:

<pre>
ELAST_EXECUTABLE = elo
GOSIA_EXECUTABLE = /home/someuser/gosia/gosia
BRICC_IDX_FILE = /home/someuser/programs/bricc/BrIccFOV22.idx
BRICC_ICC_FILE = /home/someuser/programs/bricc/BrIccFOV22.icc
RACHEL_DIRECTORY = /home/someuser/programs/rachel
</pre>

The paths should be changed to locate the three files (the Gosia executable and the two BrIcc database files) and the directory in which the Rachel files have been installed.
