Confusing licence badge on README.md

[palto42]

The README.md shows an Apache-2.0 license badge, but on the LICENSE.txt page it states 'BSD 2-Clause "Simplified" License'.

Can you please clarify which license is correct and update either the README.md or the LICENSE.txt file?

Noticed that the license information in setup.py is also inconsistent.

In the basic section it states license='Apache License, Version 2', but in the classifiers section it states License :: OSI Approved :: BSD License

Since the LICENSE.txt is BSD 2-clause, I'm assuming that this is the correct and valid license. Although both mentioned licenses are similar, the BSD is a bit more permissive as far as I'm aware.
