Code is in eval, along with two example macros.  ftsParticleGun.C to generate events, and runFtsSim.C to run the fast simulator, saving hits in the event.root file.

Check correctness -- pull distributions:

Figure 1 -- Strip pull distributions in X



Figure 2 -- Strip pull distributions in Y


Figure 3 -- Wire pull distributions in X



Figure 4 -- Wire pull distribution in Y




Figure 5 -- Bz component vs Y and Z (at x=0).  Two lines show the eta=2.5 and eta=4.0 limits.



Figure 6 -- By component vs Y and Z (at x=0).  Two lines show the eta=2.5 and eta=4.0 limits.
