v2.0.1

• Add # -*- coding: utf-8 -*- to the file.
• Switch to a single file module as a package is unnecessary since we only need one file.
• Remove __github__ constant.
• setup.py now imports the module instead of duplicating information. This should be irrelevant to users, especially since wheels avoid the setup file.

This release should hopefully not break any existing code.

I don't think anyone would use the __github__ constant so I deemed it unecessary.

The other case I can think of is that it may break the use of import stopwatch.stopwatch since previously it was a package, but that scenario was never intended to be supported.
