documentation enhancement request: How to use a newly defined board layout dict?

[villares]

I understand how to structure the dictionary from the Mega board example, and I saw in the source code how some shortcut classes that inherit from Board are written, but it looks very confusing for me. Could the documentation show a complete example on how to use a customized board?

Otherwise, could a helper function be made to make it simple to initialize a connection (board instance) passing a board layout dict?
