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