PCGoals:

--------------------------------------------------------------------------
   Generate the geometric goals for a cluster in a projected circular formation.

   Since version 7.
--------------------------------------------------------------------------
   Form:
   g = PCGoals( R, alpha0, sgn, y0 );
--------------------------------------------------------------------------

   ------
   Inputs
   ------
   R               (1,n)  radius of the projected circle   [km]
   alpha0          (1,n)  angular offset around circle     [rad]
   sgn             (1,n)  orientation of plane
   y0              (1,n)  along-track offset               [km]
                          (optional, default is y0 = 0)

   -------
   Outputs
   -------
   g                (.)   array of geomtric goals data structures

--------------------------------------------------------------------------
   Note: Each input must either be an array of length n, or a single number.
