template<class Class, int N>
struct gtsam::LieGroup< Class, N >

A CRTP helper class that implements Lie group methods Prerequisites: methods operator*, inverse, and AdjointMap, as well as a ChartAtOrigin struct that will be used to define the manifold Chart To use, simply derive, but also say "using LieGroup<Class,N>::inverse" For derivative math, see doc/math.pdf.

static Class	Retract (const TangentVector &v)
	Retract at origin: possible in Lie group because it has an identity.

	LocalCoordinates at origin: possible in Lie group because it has an identity.

static Class	Retract (const TangentVector &v, ChartJacobian H)
	Retract at origin with optional derivative.

static TangentVector	LocalCoordinates (const Class &g, ChartJacobian H)
	LocalCoordinates at origin with optional derivative.
