## Detailed Description

Interface to underlying groups for turning point calculations using the Moore-Spence formulation.

This abstract class provides the required interface for underlying groups to locate turning points using the bordering algorithm for the Moore-Spence turning point formulation (see LOCA::TurningPoint::MooreSpence::ExtendedGroup for a description of the governing equations).

This class is derived from the LOCA::MultiContinuation::AbstractGroup and declares several pure virtual methods compute various derivatives of for a given . Default implementations for the derivatives using finite differencing are implemented in the LOCA::TurningPoint::MooreSpence::FiniteDifferenceGroup.
