Calorimeters

While simulation of tracking detectors is rather straight-forward, and the method above is really all there is to it, this is not the case for calorimeters. There are many different designs for calorimeters, yielding different properties, in terms of energy-dependence of the resolution, of the precision with which the position of the the shower can be measured, of the possibility to separate hadrons from electrons or gammas, of the possibility to separate different showers, etc. Therefore, we have implemented a default simulation that is, we believe, a reasonable compromise, along with a separation between finding which calorimeters the particles will hit, and the actual simulation of the response. This separation should make it reasonably easy for the user to plug in a completely different simulation if needed.
