MNELIB::MNENearest records, for each vertex of an MNESourceSpace, the index of and distance to the closest vertex of the full cortical surface. It is the structure stored under FIFF_MNE_SOURCE_SPACE_NEAREST / _NEAREST_DIST and is used to map decimated source-space values back onto the dense cortex for rendering and morphing.
