>From the name, I infer that this is an object that captures the information
from the <bcalTruthIncidentParticle> tag in the simulation event hddm
record. Any time a particle in the MC simulation enters the bcal through
the inner surface, its coordinates, type, and momentum are recorded in a
<bcalTruthIncidentarticle> tag that gets added to the output event. At the
same time, a stamp is placed on that particle so that neither it nor any
secondaries descended from it can create further
bcalTruthIncidentParticles. This keeps shower particles from getting
appended to the list and making it confusing to interpret.
I am not sure nowadays who might be making use of that information, but it
has a clear meaning and is potentially useful in Monte Carlo studies for
computing efficiencies and adjusting matching windows, etc.
