prtNewRegress creates a new prtRegress* M-file
 
    prtNewRegress creates a new prtRegress* M-file including definitions for
    all required methods and properties for prtRegress objects.  By
    convention, prtRegress M-files should start with the string prtRegress, and
    file names must be valid MATLAB function names (no special characters,
    spaces, etc.)
 
    prtNewRegress(FILENAME) enables the user to specify the name of the new
    prtRegress object from the command line.
 
    %Example:
    prtRegress('prtRegressAwesome');
