Release Optimize QMix · garrettj403/QMix

Optimization

Added more detailed benchmarking and profiling scripts (found in QMix/profile/).
qmix.qtcurrent.qtcurrent is now ~20% faster for 1 tone.
qmix.harmonic_balance.harmonic_balance is ~20% faster for 1 or 2 tones, and ~10% faster for 3 tones.

Renamed cct.vph to cct.freq (in qmix.circuit.EmbeddingCircuit). The normalized photon voltage is equivalent to the normalized frequency. I think frequency is easier to understand so I changed it.
Deleted the command line scripts (bin/). There was only one script and it was pretty obscure so I descided to delete it.
Moved qtcurrent_all_freq() function from qmix.qtcurrent to qmix.harmonic_balance. Again, it's a pretty obscure function and it's only used in the harmonic_balance module, so I moved it.
Deleted qtcurrent_std from qmix.qtcurrent. This function calculated the "standard" output values, but this was pretty arbitrary. It also didn't really simplify the package at all so I deleted it.

Travis CI now automatically rebuilds the online documentation on each new commit.
Added information on how to contribute to QMix to README.
Added docstrings to many private functions. This should allow new users to understand the inner workings a bit better.
