List of models for the astropy core

This is a list of models we plan to put into the astropy core before the 0.3 release. Discussion: https://github.com/astropy/astropy/issues/981

Here's the list of models already in astropy.modeling.models: http://docs.astropy.org/en/latest/models/index.html

These lists were generated by going through these lists and selecting the models that seem general and often-used enough to be in astropy core:

beta1d and beta2d
box1d and box2d
delta1d and delta2d
disk2d: constant within some radius.
king2d
lorentz1d and lorentz2d
voigt - this can be implemented as the convolution of lorentz1d and gauss1d
poisson
schechter
shell2d
sersic2d
Gauss-hermite series e.g. in astropysics - some of the stuff in numpy.polynomial.hermite may be helpful here
Power law. In Sherpa and GammaLib - see PR #1184, this will probably be in soon
Exponential cutoff power law. In GammaLib
Broken power law. In sherpa and PyModelFit
Curved power law. In sherpa and GammaLib

Navarro, Frenk, and White 1996 profile – the canonical dark matter halo profile; in Astropysics
Generic alpha-beta-gamma models common in mass modeling (NFW is a subset of this) in PyModelFit
Plummer sphere (Plummer 1911) in Astropysics
King2D
King3D - this is the deprojected version of king2d

Table models (see tablemodel in Sherpa or LinearInterpolatedModel or NearestInterpolatedModel in PymodelFit 1D and 2D table models in GammaLib) with a few interpolation options. This is very important but I think should be discussed in a separate issue, with the discussion here focusing on "analytical" or "functional" or "mathematical" models.

To avoid duplication of effort if you intend to work on implementing a new model please create an issue on github stating so.
