Description:
 def modifydocs(a, b, desc=''):
 """ Convenience function for writing documentation. For a class method `a` that is essentially a wrapper for an outside function `b`, rope in the docstring from `b` and append to that of `a`. Also modify the docstring of `a` to get the indentation right. Will probably deprecate this soon. **Parameters** 		**a** : class method 			Class method wrapping `b`. 		**b** : function 			Function wrapped by `a`. 		**desc** : string, optional 			Description of `b`, e.g. restructured text providing a link to the 			documentation for `b`. Default is an empty string. **Returns** 		**newdoc** : string 			New docstring for `a`. """
