First steps

• Simulating a drift tube: gas tables, analytic fields, Runge-Kutta-Fehlberg integration of drift lines, signals.
• Simulating a GEM: finite element model, microscopic tracking of electrons.
• Simulating a planar silicon sensor: user-parameterized fields, strip/pixel weighting fields, Monte Carlo integration of drift lines, signals.
• Simulating a Resistive Plate Chamber: parallel plate geometry, Legler model, grid-based Monte Carlo simulation of avalanches, and space-charge effects.
