% Perform targeting using the Lambert algorithm.
Takes the states of two spacecraft at an epoch and a transfer time
and performs Lambert targeting. Returns the delta-V and a flag for the
long or short transfer.
See also LambertTOF.

Form:
[dV,tM,okFlag] = DVTarget(r1,v1,r2,v2,dT)
--------------------------------------------------------------------------
------
Inputs
------
r1 (3,1) Position of spacecraft 1 (km)
v1 (3,1) Velocity of spacecraft 1 (km/s)
r2 (3,1) Position of spacecraft 2
v2 (3,1) Velocity of spacecraft 2
dT (1) Transfer time (s)
-------
Outputs
-------
dV (:) Struct of delta-Vs
.a (3,1) First delta-V (km/s)
.b (3,1) Second delta-V (km/s)
tM (1) Flag: +/-1 for short/long transfer
okFlag (1) Flag: 1 if maneuver is OK, 0 if hits the Earth
