[IPython-dev] Flat is better than nested

[Carlos Córdoba]

Hi,

@Aaron: A @public decorator seems really cool, it makes look code really 
neat! I'll investigate how to include it in our PR.

@Trevor: I think you are missing the point: these changes are not meant 
for regular users but for projects that are using IPython as a library. 
The idea is to put in __all__ the main pieces of qtconsole (not only 
RichIPythonWidget, but also QtKernelManager, QtKernelClient, etc) to 
tell those projects what elements they need to rely on to build a 
customized frontend.

Cheers,
Carlos
