Thanks again to Alondria for adding: math support for

rot * rot, vec / rot, == and != overriders for Rotations and Vectors.
Also: llRotBetween(), llGetRegionTimeDilation(). And fixing:
Error in LSL2CSConverter that botched a variable with a type name in it (ex: rotationCenter)
Fixed: Error in LSL2CSConverter that parsed which() loops incorrectly.
Fixed: Changed definition of Quaternion to <x, y, z, r> from <x, y, z, t> (As per LSL)
Finished: llEuler2Rot()
