MNELIB::MNESourceSpace replaces the mneSourceSpace typedef of mne_types.h and is the C++ representation of one decimated source space stored under the FIFFB_MNE_SOURCE_SPACE block in a forward / inverse FIFF file. It holds the dense surface (vertices, triangles, normals, neighbouring relations) plus the subset selected by the MNE decimation (inuse / nuse / vertno) used to index the leadfield columns of MNEForwardSolution. The structure is consumed by MNESourceSpaces (left+right pair), MNEHemisphere, the BEM tools and every clustering or morphing step in the inverse pipeline.
