rm scipy version requirement, because it only matters for a few functions [ci skip]
update statement about how long the test suite takes [ci skip]
add vt response, should be tested (currently covered)
add test of periods interface with isochroneApprox
fix the documentation of tsteady
doc tweak for scatterplot [ci skip]
Dehnenbar doc tweak [ci skip]
documentation tweaks for non-axisymmetric potentials to clarify use of tform and tsteady; change the definitionof tsteady for DehnenBar to make it consistent with the other potentials
documentation on galpolar and how it fails with newer versions of matplotlib
full testing of the orbit-fitting routines, #165
add orbit fitting routine to the API, fixes #165
separate out the pvRvT etc. tests in qdf, because these can take a loooooong time on travis (even though they only take 50 seconds on my laptop)
add tests of evolveddiskdf for cold population (compare with analytical prediction), fixes #196
fix actionAngleIsochroneApprox plotting with integrated orbit, fixes #181
add documentation of virial quantities to the API, #129
add tests of conc, rvir, mvir, and NFW setup #129
few more tests of the potential masses, add caveat to docs about spherical masses with not z is None
add hasC_dxdv attribute to indicate whehter or not this potential has C implementations of the second derivatives to allow for phase-space volume integration, fixes #176
