Added a new class in halo_occupation for Leauthaud HOD
Minor changes to API of Zheng07 HOD
Merged Alexie's SMHM-based HOD into the halo_occupation module.

Merge remote-tracking branch 'upstream/develop' into develop
Alexie's SMHM HOD does not work when passed an array of halo masses.
The class runs just fine when passed a single halo mass,
but breaks when any of the methods are passed a numpy array of many halo masses.
The root of the problem appears to be the use of the brentq routine in scipy.
This routine apparently does not want to its optional args input
to be array. It's not immediately obvious how to get the correct
vectorized behavior.
