Detailed Description

Creating Jacobian of transformation within the curvilinear frame. The basic functionality of this class is to provide the (analytical) Jacobian matrix of the transformation within the curvilinear frame from the state defined by globalParameters to the state defined by x and p. This Jacobian can then be used to yield the corresponding error propagation. The current implementation is based on the original derivations by W. Wittek. However, due to the implicit float precision, two terms ((4,1) and (5,1)) have been modified in order to make the calculations more stable in a numerical sense.
