INVLIB::InvGuessData generates and stores the regular grid of candidate dipole positions that seeds the Nelder-Mead optimiser used by InvDipoleFit. For every guess location the corresponding forward-field SVD is pre-computed into an InvDipoleForward, so the per-iteration evaluation cost reduces to a dense matmul. Replaces the guessDataRec record of MNE-C and is built either from a user-supplied guess source space or directly from an inner-skull BEM surface inflated to a regular (mindist, exclude, grid) lattice.
