	These functions perform the transport of a covariance matrix using given Jacobians. The required data is provided by the stepper object with some additional data. Since this is a purely algebraic problem the calculations are identical for StraightLineStepper and EigenStepper. As a consequence the methods can be located in a seperate file.
