 BULLETSIM TODO LIST:
 =================================================
-Avatar density is WAY off. Compare and calibrate with what's in SL.
+Implement an avatar mesh shape. The Bullet capsule is way too limited.
+        Consider just hand creating a vertex/index array in a new BSShapeAvatar.
 Revisit CollisionMargin. Builders notice the 0.04 spacing between prims.
 Duplicating a physical prim causes old prim to jump away
         Dup a phys prim and the original become unselected and thus interacts w/ selected prim.

 Re-implement buoyancy as a separate force on the object rather than diddling gravity.
         Register a pre-step event to add the force.
 More efficient memory usage when passing hull information from BSPrim to BulletSim
+Avatar movement motor check for zero or small movement. Somehow suppress small movements

 LINKSETS
 ======================================================
+Offset the center of the linkset to be the geometric center of all the prims

 =================================================
+Create the physical wrapper classes (BulletBody, BulletShape) by methods on
