Add mass_profile tools

* These tools are mainly use to calculate the total gravitational mass
  profile, as well as the intermediate products (e.g., surface
  brightness profile fitting, gas density profile, NFW fitting, etc.)
* There are additional tools for calculating the luminosity and flux.
* These tools mainly developed by Junhua GU, and contributed by
  Weitian (Aaron) LI, and Zhenghao ZHU.
