Detailed Description

======= VXDClusterParameters ==========
Holds cluster parameters for a VXD hit - to be attached at runtime to the SimTrackerHit.

Cluster is defined by two (principal component) axis and the corresponding extensions (eigenvalues).

Constructor & Destructor Documentation

VXDClusterParameters::VXDClusterParameters	(	const gear::Vector3D &	localPos,
		const gear::Vector3D &	a,
		const gear::Vector3D &	b,
		int	lay,
		int	lad
	)

The standard constructor: takes the position of the hit in ladder coordinates and the cluster axes in ladder coordinates.

Also store the layerId and ladderId for saving cpu time later.
