Fix the rest of things up for fixed instead of strided dimensions

* neighborhood_iter tests were crashing, removed these as
  probably not worth the time maintaining them vs neighborhood
  arrfuncs
* neighborhood arrfunc depended on some details of strided
  pattern matching, inserted a hack in the resolve_dst_type
  that needs some more design/implementation work on the
  datashape pattern matching
* a small addition to nd::view to allow viewing var as fixed
