Document how depos may be dropped #27

Put this in the manual.

Downstream of Drifter Depos can be rejected for a few reasons. A depo is dropped if:

1) it is outside of an AnodePlane's "bounding box". Transversely, this is set by the envelope of the wires.

2) it is not between the hypothetical (and maybe badly named) "anode" and "cathode" planes. The latter should coincide with the face of the physical cathode (but need not) and the former is chosen some place "close" to the wires. That "anode" plane sets a trade-off in approximation of what to do with depos that are made inside the field response region. I think we pick X=1cm (U wires are at X=0 in MB) but maybe want to go tighter.

3) it is outside of the Ductor's time "gate". If using "fixed" mode they are dropped. If using continuous mode their waveforms will be put in the next readout.

4) it is in an ignored wire region when using a multiple-ductor setup.

Maybe I forget others and one other depo related thing is:
