Detailed Description

Class describing the decay chain inside the kinematic fit. Uses the boost graph based DDD library. KinematicVertices are vertices, kinemtaic particles become nodes.

Kirill Prokofiev, April 2003 WARNING: before using any of these methods please make sure you understand correctly what part of tree are you looking at now and where the pointer will be after the desiring operation.

"Left" and "Right" notation reflects the order of creating a three: from bottom to top, from left to right EXAMPLE: Bs->J/Psi Phi -> mumu KK First creating a mumu branch, fit it to J/Psi, Then adding Phi->KK and reconstructing a Bs will look like: left bottom particle: muon, top of the tree is Bs, right bottom is K.

void KinematicTree::addTree	(	RefCountedKinematicVertex	vtx,

Method adding a tree tr to the vertex vtx of current tree in such a way, that vtx become a production vertex for the top particle of the tr. The whole contetnts of tr is the rewritten to current tree. This method is purely technical and contains no mathematics. To be used by KinematicParticleVertexFitter after the corresponding fit.
