 52  """ 
 53  Python product that fullfills a simmilar function as ExternalMethod 
 54  except that will call any callable, mostly classes that inherit from 
 55  the mode class below, instead of just Python functions. (Remember, 
 56  calling a class will return an instance). The callable MUST have a 
 57  **kw parameter for arbitrary key word arguments for this to 
 58  work. Anyway, think of modes as External Methods which have 
 59  overloadable parts.
