start on re-working actionAngle in the orbit framework
move setupaA to OrbitTop
'fix' setup in actionAngle
raise error if orbit isn't a FullOrbit
change other actions and angles
remove wp and setupaA from sub-orbits
also write periods in terms of new actionAngle modules
also add the frequencies
add frequencies to docs
remove unnecessary imports
better parsing of actionAngle input for planar orbits
calculate rperi, rap, and zmax in actionAngleAdiabatic
remove unnecessary imports
switch to using new actionAngleAdiabatic rperi, rap, and zmax computation in analytic calculation in Orbit framework
also use new actionAngle Orbit framework to calculate rperi, rap, and zmax for RZOrbits
some hacks to make actionAngle calculations work somewhat better for planarOrbits, but still not quite right (should use actionAngleAdiabatic
