RFE: rename module to 'igor'

[keszybz]

I don't care about the name of the pypi module… But having the importable module under a different name is a royal PITA: every user of the module would have to be adjusted. This module is a low-level building block, so those imports are often buried deep in some library code. Please rename the module so that it remains a drop-in replacement.

What's the general feeling here? Should we give it a vote?

Or can we make it so that igor becomes an alias to igor2? Not sure whether Python allows such magic.
