1	'''
2	This module provides three model editor classes: the composite model editor,
3	the 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
6	standard available math functions. Finally a full python editor panel for
7	complete customizatin is provided.
8
9	:TODO the writiong of the file and name checking (and maybe some other
10	funtions?) should be moved to a computational module which could be called
11	fropm a python script. Basically one just needs to pass the name,
12	description text and function text (or in the case of the composite editor
13	the names of the first and second model and the operator to be used).
