Use Eigen types in RungeKuttaUtils::transformPlaneToGlobal

Currently, the transformPlaneToGlobal method in the Runge Kutta utilities package uses bare arrays of doubles. This means that data needs to be copied out of AMG (Eigen) vectors in order to use them there. In some cases, this happens twice. This commit changes the signature of this function to take AmgVector(5) references as argument instead, which should reduce data copying a little, and bring the method more in line with the design of the track parameter classes.
