ens_initConfig

PURPOSE ^

Reads the contents of the specified GUI config file

SYNOPSIS ^

function [c] = ens_initConfig( fname )

DESCRIPTION ^

 Reads the contents of the specified GUI config file
 and puts the results into the return stuct "c" which will become 
 the "config" field of the main GUI data struct. 
 Checks for data validation and setting default values for missing
 variables are all done here.
 
 To add a new variable, you only need to add it to the config file,
 check for its value here, and assign it to a position within the
 return struct "c". Then the main GUI can do whatever it wants with it.
