MNELIB::MNEProjOp is the operator form of the SSP machinery: it stacks the active projection vectors into an orthonormal basis and applies the corresponding rank-one removal to sensor data, leadfields or noise covariances. Used by the raw, evoked and forward paths to keep all data products in the same projected subspace.
