TYPE: POP
TITLE: SoftBody POP

The Softbody POP performs soft body deformations. The edges of the
geometry act as "springs" which act to pull the points back toward
their original shape. 

Parameters:
    Activation        - Turns the POP on and off	/activate
Source
    Geometry Source   - Specifies where the POP should get
                        the softbody Object and SOP
    SOP               - SOP containing geometry
    Ignore Transform Object - Transform geometry to transform object space
    Fixed Points      - Points to be considered stationary 
    Fixed Points go to Source Positions - Fixed Points are put to
			their positions in the Source.
    Copy Groups from Source - All Source groups are copied at each frame.
                        Useful if the Fixed Points group contents are animated.
    Hide particle system - Make the particle system that controls the softbody
                           deformation hidden (i.e. does not show in scene).
Spring
    Spring Behavior   - How the springs will behave
	Hooke's Law            - Use Hooke's law. 
                                 Force = displacement x spring constant.
	Normalize Displacement - Like Hooke's law except displacement is 
                                 normalized to the original length of the 
                                 spring. (Behavior used in Houdini 2.5).
	No Springs             - No springs will be used.
    Spring Constant   - Stiffness of the spring			/springk
    Initial Tension   - Initial spring tension before deformations	/tension
Attributes
    Create Local Variables   - Create local variables corresponding to
                               inherited attributes.
    Add ID Attributes        - Add ID and parent attributes
    Add Generation Attribute - Add generation attribute
    Add Origin Attribute     - Add origin attribute
    Use as Origin            - How to set the origin
    *Origin Index            - Index as used in origin		/originindex
    Add Speed Attribute      - Add speed attribute (length of velocity vector)
