* igraph_community_leading_eigenvector_callback_t type.
* The following arguments are passed to the callback:
* \param membership The actual membership vector, before recording
* the potential change implied by the newly found eigenvalue.
* \param comm The id of the community that the algorithm tried to
* split in the last iteration. The community ids are indexed from
* zero here!
* \param eigenvalue The eigenvalue the algorithm has just found.
* \param eigenvector The eigenvector corresponding to the eigenvalue
* the algorithm just found.
* \param arpack_multiplier A function that was passed to \ref
* igraph_arpack_rssolve() to solve the last eigenproblem.
* \param arpack_extra The extra argument that was passed to the
* ARPACK solver.
* \param extra Extra argument that as passed to \ref
* igraph_community_leading_eigenvector().
*
* \sa \ref igraph_community_leading_eigenvector(), \ref
