    22This module provides three model editor classes: the composite model editor, 
    33the easy editor which provides a simple interface with tooltip help to enter 
    4 the parameters of the model and their default value and a panel to input a  
    5 function of y (usually the intensity).  It also provides a drop down of  
     4the parameters of the model and their default value and a panel to input a 
     5function of y (usually the intensity).  It also provides a drop down of 
    66standard available math functions.  Finally a full python editor panel for 
    77complete customizatin is provided.
