Detailed Description

Helper class to provide unique numerical ID's for Alignables. The unique ID is formed from:

• the AlignableObjectId (DetUnit, Det, Rod, Layer, etc.)
• the geographical ID of the first GeomDet in the composite. A mapping between the AlignableObjectId and the string name is also provided.

typeAndLayerFromDetId()

std::pair< int, int > TrackerAlignableId::typeAndLayerFromDetId	(	const DetId &	detId,
		const TrackerTopology *	tTopo
	)		const

Return type and layer of DetId Keep this for now. Concept of a "layer" in Alignment is obsolete. Will be replaced by a more generic function.
