- moved some arguments around in connect_iterate and coords_iterate functions
- moved iterator #define's to iBase_f.h.in from iMesh_f.h
- implemented new imesh extension functions iMesh_connectIterate and iMesh_coordsIterate, which provide direct access to 
  memory used to store connectivity/coordinates, resp.
- added an argument to get the # vertices/entity to connect_iterate
- implemented new iMesh extension function iMesh_initEntArrIterRec, which is an iterator that recurses into contained
  entity sets; all other iterator-related functions operate as before, but with recursive access to sets (this also
  required changes to implementation in MBIter, but since MOAB's underlying functions already had a recursive flag,
  this just involved storing/sending the flag to the MOAB function
- in vtkMOABReader, implemented more careful determination of vtk cell type, and support quadratic cell types in some
  cases

Passes make check.
