Namespaces
namespace	gtsam
	Global functions in a separate testing namespace.

Macros
#define	EXPECT_RIGHT_ACTION(phi, m, g1, g2)
#define	EXPECT_LEFT_ACTION(phi, g1, g2, m)

Enumerations
enum class	gtsam::ActionType { Left , Right }
	Enum to specify whether the action is a Left or Right action.

Functions
template<class Action, class M_, class G_>
bool	gtsam::rightActionEqual (const Action &phi, const M_ &m, const G_ &g1, const G_ &g2)
	Check right action property: φ(m, g1 g2) = φ(φ(m, g1), g2).
template<class Action, class G_, class M_>
bool	gtsam::leftActionEqual (const Action &phi, const G_ &g1, const G_ &g2, const M_ &m)
	Check left action property: φ(g1 g2, m) = φ(g1, φ(g2, m)).
