MNELIB::MNEForwardSolution is the in-memory representation of an -fwd.fif file: the leadfield matrix, the source spaces it was computed on, the sensor coordinate transforms, the projection vectors and the source-orientation flags. It is the central input to inverse modelling (MNEInverseOperator), to cluster-based dimensionality reduction (cluster_forward_solution) and to simulation routines. FIFF tags involved: FIFFB_MNE_FORWARD_SOLUTION, FIFF_MNE_FORWARD_SOLUTION_GRAD, FIFF_MNE_SOURCE_ORIENTATION, FIFF_MNE_COORD_FRAME.
