Missleading javadoc for method in Orbit class

Hi everyone,

I find the documentation of initPVCoordinate incomplete. It only states that position and velocity vectors are computed, but in fact the acceleration is also concerned. I think it is worth indicating as in case of time derivatives present, there will be an increased computational burden (due to a Jacobian matrix I believe) that seems to be non negligible in some applications, and useless if the end goal is independent of the acceleration (this brings another point: it’d be nice to have a method to clear those derivatives, or am I missing it?).
Per se it’s not dramatic that the description is missleading because the method is protected, but it can be called within the public one getPVCoordinates.
