Title: NF: Surface disk neighborhood + Surface searchlight

Add a new neighborhood/query engine SurfaceDisk, which behaves like an IndexedQueryEngine. Using Freesurfer surfaces and corresponding vertex volumes produced by `mri_surf2vol --vtxvol`, this query engine accepts a voxel index and returns the indices of voxels within a radius along the intrinsic geometry of the cortex.
