CPhysicsProp

is a code class inherited by most physically-simulated model entities.

Classnames:
 * - Generic entity used for models that move freely and realistically. Models need to have physics checked in the model browser in order to be used.
 * - Older name, automatically converts to  after spawning. No reason to use it.
 * - Can be used to override the prop data settings and use any model as a physics prop. Normally models are restricted to one or two types of props (dynamic, static, or physics). Automatically changes classname to  after spawning. It can also be used to set a custom Health amount.)
