TYPE: CHOP
TITLE: Particle CHOP

This CHOP produces translate and rotate channels to move Objects according to
the positions of particles in a POP Network. Channels are generated for all
particles with an instance attribute and which have the override state
turned on.

There are no local variables.

Parameters
Particle
    POP Path      - POP to cook.
    Method        - Specifies whether the CHOP should generate channel
		    values for the current frame (Dynamic) or for all
		    frames at once (Cached).
    Extract Scope - Specifies a mask of channels to generate.
    Update        - Forces an update of the CHOP if it is in Static mode.
    Start Time    - Time at which simulation starts	/timestart
    Preroll Time  - At start time, simulation has already been running
		    this long	/timepreroll
    Initial State - geometry to use as initial state of simulation
    Oversampling  - How many times to cook in between frames	/oversample
    Max # of Particles - Controls the maximum number of particles that
			 can exist in the simulation at any given
			 moment. A value of 0 means particles can
			 always be birthed.	/maxparticles
    Remove Unused Points - Remove unused points from input geometry.
    Rest Threshold    - The minimum relative velocity two RBD particles
			must have to be considered colliding.	/restthreshold
    Contact Tolerance - The distance at which RBD particles are treated
			as being in contact.	/contacttol
    Max Time Splits   - A measure of how accurately RBD collisions
			should be detected.	/maxdivisions
    Constraint Time    - Approximate time allowed to satisfy RBD
			 constraints.	/constrainttime
    Solver Type        - Type of solver to be used by the RBD solver.
    SOP 1-4       - The paths of SOPs to use as Context Geometry.
Channel
    Start, End    - The start time of the channels.           /start, end
    Sample Rate   - The sample rate of the channels.          /rate
    Extend Left   - The left extend conditions.
    Extend Right  - The right extend conditions.
    Default Value - The default value for extend conditions.  /defval
