Detailed Description

Base class for Intersector AlgTools.

Returning a NULL pointer means that the intersection/approach has not converged, or there has not been a mathematical solution for this.

modifications from Alan..nosp@m.Popp.nosp@m.leton.nosp@m.@cer.nosp@m.n.ch:

• I've added a preliminary set of interfaces that are sufficient to get me going.
• The TrackParameter interfaces are just a suggestion - there is no implementation.
• I've not included PropDirection as the code discovers this by itself !
