Parse cisco's "show ip route" output in Python 2.7

[Dan Stromberg]

I've done little with Ciscos,  but what if you use individual things like
 "show ip ospf", "show ip rip database", etc. instead of "show ip route".
Does that makes things a little more consistent?

Often big problems are simpler if we can divide them into smaller, more
manageable subproblems.
