Detailed Description

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

This abstract class provides the required interface for underlying groups to locate pitchforks using the bordering algorithms for the Moore-Spence pitchfork formulation (see LOCA::Pitchfork::MooreSpence::ExtendedGroup for a description of the governing equations).

This class is derived from the LOCA::TurningPoint::MooreSpence::AbstractGroup and declares a single virtual method, innerProduct(), to compute the inner product of a vector with the asymmetry vector. It has a default implementation given by the dot product, but should be overloaded for any problem that has a different definition for the inner product.
