I like the result!

Three (small) problems:

* Running the icap command a second time doesn't show any output to the 
terminal while running.
* The example in the docstring uses ix() instead of icap().
* icap should be added to __all__, so it's available after
     from ipipe import *

In what way does it differ?

Well, it uses curses, but the state of the terminal should be reverted 
to the previous state, as it uses curses.wrapper()
