STM Tagger porting

[brettviren]

The "STM tagger" portion of WCP is ported to WCT primarily in order to validate the Steiner related porting (#431).

This is a meta issue to organize that task. Here is an initial list of features needed and notes on how to provide them:

• Is a point inside the fiducial volume.
  • IFiducial components provide this already.
  • Includes "box" and "multi box" (per APA box) and "pnpoly" shapes.
  • Some SPE analysis is needed to provide actual pnpoly shape.
• Is a point inside a "dead volume" (defined by wires on "dead" channels).
  • WCT already make "dead" clusters.
  • WCT has at least the primitive operations to answer "is a given point inside any blob in any 'dead' cluster".
• An initial modeling of shower/track/segment data.
  • Full modeling is part of later track fitting porting (Multi-track fitting porting #437)
  • Will try to provide that so it can be used here.
• "track fitting functions".
  • Does this require an optimization engine?
  • Remember what RESS uses and see if it is appropriate, else go shopping.
• A K-S histogram test
  • WCT uses boost::histogram already, check if that is the right direction.
