Detailed Description

Fundamental type for a particle.

This class contains everything that a "dark matter" particle needs. Other classes of particles require this plus an "extra data" class.

cosmoType GravityParticle::dtGrav

timestep from gravity; N.B., this is actually stored as (1/time^2) since the gravity calculation naturally gives us (G M/R^3).
