Python Script - Generate Possible Set of Corporate Usernames

This code is not a big deal, however useful. You pass a name like "Navtej Singh" to the function and it will churn out a list of possible usernames. This list can then be used for various tasks including bruteforcing, in bots etc. The generated list of usernames is such that it fits in the corporate email id model better than for public email id's. So for sites like yahoo etc, avoid it. On yahoo, Gmail, Hotmail etc "Jonny Walker" can be high_on_alcohol, however this is (with approx) not true for corporate email IDs.

The output for "Navtej Singh" is :
navtejsingh, navtejs, navtej, navtej.singh, nsingh, navtej.s, singh, ns, n.singh

and for "Navtej Singh Buttar" is:

navtej.singh.buttar, navtejsinghb, navtej.buttar, n.s.buttar, navtejbuttar, navtejsingh, nsb, nbuttar, navtejs, navtej.b, navtej, navtej.singh, nsingh, buttar, navtejsinghbuttar, navtej.s, nsbuttar, n.singh, navtejb, n.buttar

Enjoy it...BTW if you find certain ids not given by the script and those ids are very logically deduced from the given name, inform me .
