pow_dense

[MrRobot2211]

This implements pow and creates a class that should be inside QuTiP proper to do the testing.

We can afterwards add the test class to qutip and inherit here in future PRs.

This in pursuit of having the most functionality available on the "first" release.

This is ready to merge after extra_functions

The class PowTest is now merged in dev.major. :)

@hodgestar I think this is ready then, I'll inherit from the newly minted QuTiP tests later on.

@MrRobot2211 Approved! Happy for you to merge once the test run passes.

@MrRobot2211 Could you fix up the silly pep 8 errors resulting from my merging with GitHub's merge interface? Apologies for leaving you with the mess but I am stepping away from my computer now and don't have the branch checked out to do the clean up quickly.
