@routine ParseFile
@author Paul Walker
@desc
This routine actually parses the parameter file. The
syntax we allow is
<ul>
<li>a = b
<li>a,b,c = d,e,f
<li># rest of the line is ignored
<li>x = "string value"
</ul>
So it is easy to parse
<p>
We go through the file looking for stuff and then set
it in the global database using calls to the passed in set_function.
