re-write action tests to be more general
basic tests of actionAngleSpherical; don't cover some setups
perform spherical tests also for fixed_quad; don't cover no-phi case
more spherical actionANgle tests: basic tests of actions and comparison w/ isochrone potential
cover some more cases of spherical, found problem w/ close to circular orbits
fixes to allow for lists of potentials
start on some actionAngleAdiabatic tests, remove eccentric orbit test
test whether actions are conserved for actionAngleAdiabatic
rm unused code in actionAngleAdiabatic (cleaning up)
more extensive tests of various actionAngleAdiabatic options
don't cover lib loading
don't cover parts of actionAngleAxi that aren't supported currently, rm some unnecessary code
don't cover parts of actionAngleVertical that aren't supported currently
start on actionAngleStaeckel tests, start w/ estimateDeltaStaeckel
basic testing of actionAngleStaeckel
further testing of actionAngleStaeckel
bunch more actionAngleStaeckel tests
further testing of estimateDeltaStaeckel
don't cover not being able to load the library
tests comparing actionAngleStaeckel to isochrone actions
