@ashfurrow => RACify the keypad view

Keypad input sends is a stream man.
The bid view controller subscribes and passes sends the input to a textfield.

RAC Tests well using Dependency Injection, good advice on that. The technique is just changing the RAC stream that fakes the  keypad input triggers so that in tests it's runtimeable. Cool. :+1: 
You are not using the casted 'view' ;)

I'm curious: what's your opinion about defining the sender parameter directly as a UIButton in the method signature? The recent versions of IB even shows the class in the dropdown which is handy :smile:
