LPCircularTimeWeight:

--------------------------------------------------------------------------
   Determine the target state on the desired trajectory that gives the minimum 
   time-weighted cost.

   Use the LPCircular control algorithm to compute the delta-v's associated with
   maneuvering from an initial state (x0) to a series of target states, which
   lie on a trajectory defined by the geometric goals (g). The target state 
   associated with the minimum time-weighted cost is returned.

   Since version 7.
