Fix example usage of BaseFormatter.for_type_by_name....
Fix example usage of BaseFormatter.for_type_by_name. I propose a small documentation fix for this excellent feature of IPython. The current example doesn't work because the type module and type name are lumped into one string. They must be given as separate strings. See docstring: ``` Signature: BaseFormatter.for_type_by_name(self, type_module, type_name, func=None) ``` For extra clarity, I have added a submodule to this made-up example module so that the pattern is clear.
