Description:  Creates a spherical joint between two objects with specified parameters. Also known as a Ball and Socket joint. (Forward/Back,Up/Down, and Left/Right movement locked, Yaw, Pitch, and Roll movement unlocked.)
Illustration of a Sphere Joint.

Parameters: 
 objects: Array  [fromObj,toObj]
 fromObj,toObj: Object  both connected objects
 jointParameters: Array  ["SphereJoint",fromPose,toPose,misc,jointDesc]
 fromPose: Array  [pos,axis]
 toPose: Array  [pos]
 pos: Vector3D or String  joint connection point in model coordinates or memory point name. (default = connectionChild/connectionParent memory point or [0,0,0] if not defined)
 axis: Vector3D or String  joint connection axis in model coordinates or memory point name. (default = connectionChildAxis memory point or up vector if not defined)
 misc: Array  [collisions,breakForce,projDist]  array of miscelaneous parameters
 collisions: Boolean  Flag to determine if we want to have enabled collisions between connected objects. (default = false, range = [true,false])
 breakForce: Number  Force needed to break a joint connection in Newtons (default = 1 ... disabled, range = <0,+inf))
 projDist: Number  Max projection distance. (default = 1 ... disabled, range = <0,+inf))
 jointDesc: Array  [limits,springs]  Sphere joint description
 limits: Array  [twistLowLimit,twistHighLimit,swingLimit]  joint limits
 twistLowLimit,twistHighLimit,swingLimit: Array  [restitution,value]  joint limit parameters
 restitution: Number  limit bounce (default = 1 ... joint limit disabled, range = <0,1>))
 value: Number  The angle beyond which the limit is active (default = 0, range = angular (pi,+pi>).
 springs: Array  [twistSpring,swingSpring,jointSpring]  joint springs
 twistSpring,swingSpring,jointSpring: Array  [enabled,spring,damping,value]  joint spring parameters
 enabled: Number  Flag to determine if we want to enable that spring (default = 0, range = [0,1])
 spring: Number  spring coefficient (default = 0, range = <0,+inf))
 damping: Number  damper coefficient (default = 0, range = <0,+inf))
 value: Number  target angle of spring where the spring force is zero. (default = 0, range = angular (pi,+pi>)
