Class Description

This is a module to take tracks, project them to the beam pipe, and
infer a vertex.  It is a poor mans way of doing what BrTPMTrackVertexModule
does (poor meaning use for pp where there are rarely more than one track)
The module can be used for TPM1 or T1 although the accuracy will depend
which detector is used and which angle it is at.
