This class contains a Properties object that is used to store all
of the parameter names and their corresponding values. It contains
a secondary Property object that is initialized with the default
values of the parameters as described in Chapter 5 of the lil-gp
User's Manual.
More importantly, this class contains all of the methods responsible
for parsing the parameter values for errors before the output file
can be generated.
This class also contains a Vector object that is used to store
errors encountered while parsing the database. Once the parse is
complete, an ErrorFrame is instantiated and the error Vector is
passed in.

are inserted to help make it readable.

reading the contents into a temporary hashtable. If it encounters any
unexpected errors in the parameter file, it will abort the open process.
That is, it will leave the current settings on all of the panels intact
and show the user where the error occurred. If there are no sytax errors
in the file, then the parameters are run through the <tt>parse()</tt>
method. If there are no errors in the parameter settings, then the
<tt>loadParams()</tt> method is called for each panel.
