* halo.py: Force a minimal value on acceleration coefficientAaron LI2017-06-011-1/+1
| | | | | | | To avoid the too small (or zero) values for the diffusion coefficient of the Fokker-Planck equation. Also change config "extragalactic/halo/pmax" from 1e4 to 1e5

* Add clusters/solver.py to solve the Fokker-Planck equationAaron LI2017-06-011-0/+276
Adopt the finite difference scheme to solve the Fokker-Planck equation, following Park & Petrosian (1996, ApJS, 103, 255).
