Detailed Description

Convenience finder of leptonically decaying Ws.

Chain together different projections as convenience for finding W's from two leptons in the final state, including photon clustering.

Todo:

Inherit directly from ParticleFinder, not FinalState

const PROJ& addProjection	(	const PROJ &	proj,
		const std::string &	name
	)		[inline, protected, inherited]

Register a contained projection. The type of the argument is used to instantiate a new projection internally: this new object is applied to events rather than the argument object. Hence you are advised to only use locally-scoped Projection objects in your Projection and Analysis constructors, and to avoid polymorphism (e.g. handling ConcreteProjection via a pointer or reference to type Projection) since this will screw up the internal type management.
