Detailed Description

Concrete class that provides concrete implementations of the derivative computation methods of the LOCA::TurningPoint::MooreSpence::AbstractGroup using first-order finite differencing.

The finite-differencing calculations are actually implemented by the LOCA::DerivUtils class, and a custom DerivUtils object can be passed through the constructor of this class. However, in the future the calculations encapsulated in the DerivUtils class may be incorporated directly into this class and other finite-differencing child classes.
