@Lucia-Fonseca would this perform simulation functions as the Vale+Ostriker implementation?

@gfavole what are some example secondary properties?

Are these properties likely to be formatted in a table/list just like the primary properties? Or, put another away, do you see the data format requiring something to change for...

Yeah, if they're easy to generate now and then they are modular so that they can be changed later, I think we can go for it?

@Lucia-Fonseca Is it correct that halotools does NOT generate initial halo information, like mass distributions?

## Ideas - lognormal distributions of properties with covariances - power-law models of properties based on basic halo properties, like mass and redshift

design flow-through links to this question: https://github.com/skypyproject/skypy/issues/147#issuecomment-615288678 We might start with this issue and one on optical properties to decide which halo properties we need?

Check in with SIBirrer about this functionality. Can lenstronomy do this test? is there a way to automatically grab the list of profiles from lenstronomy?

Make it so that we can write the functionality to automatically pull profiles/mapping from lenstronomy code instead of having static lists hard-coded
