Implements the basic model (sin/cos pairs for the HPI drive frequencies only), the advanced model (extra sin/cos pairs for the line frequency and harmonics), the cache invalidator that detects when the model has to be rebuilt, and the SVD-based pseudo-inverse that projects raw MEG samples onto per-coil drive amplitudes.
