Detailed Description

This is a lightweight type of detector element, it simply implements the base class.

The PayloadDetectorElement demonstrates how a GeometryContext can be used if it carries the entire set of Transforms through the program flow.

The nominal transform is only used to once create the alignment store and then in a contextual call the actual detector element position is taken from the alignment Store.

In this simple implementation, it does rely on the Identifier to be orderded from 0 to N-1, as the identifier is simply taken as a vector index for the alignment store
