New code

What should the nominal overbias and temperature be? I've been working under the assumptions of 1.0 V OB and 10 degrees C.
Electronic noise/dark hit smearing done with pedestal widths studied recently.
- These were single-sample widths. Do we want to emulate the f250 ADC pedestal algorithm instead (average of four samples)?
- Single sample widths are around 1.2 channels. f250PulsePedestal data output gives about 0.9 channel pedestal widths.
Poisson statistics smearing still needs a value for the energy of one dark hit.
- Elton: 0.31 MeV, deposited at the center of the module, per pixel fired. For 10 degrees, 1.0 V OB, and attenuated to the end of the module, 0.11 MeV or so. This is [current code value]/6.
The change to the data structure will be just adding 'incident_id="int"' to 'bcalTruthHit.'
- Should we also add EUP/EDN, tUP/tDN to the data structure?
- If we do not, we'll have to grab C_EFFECTIVE and ATTEN_LENGTH from the ccdb in mcsmear instead of doing it in hdgeant like usual.

I've changed the data structure and tested the output of the new code. With the old code, a hit would be up to 1 GeV or so, usually around 50 - 300 MeV.
- With the new code, I'm seeing numbers like 0.1 - 5 MeV. I'm trying to figure out where in the code I might have messed up.

Old code

We need to decide whether or not we want to keep this method available for people to choose to use.
