#2886: support cell centered directions when calling Fortran scheduled functions

 Reporter: Roland Haas
   Status: new
Milestone: 
  Version: 
     Type: enhancement
 Priority: major
Component: Cactus

The current code in git hash [eef7e55c](https://bitbucket.org/cactuscode/cactus/commits/eef7e55c0b20c4c31028adb42c6d7d52120343c1) "Cactus: use only group index based functions in Fortran wrappers" of [cactus](https://bitbucket.org/cactuscode/cactus), while removing a potential race condition does not yet correctly set up cell centered arrays for Fortran since it makes all grid functions have shape `cctk_lsh` which is the shape of a vertex centered grid function \(that is one element too large in each direction for a fully cell centered grid function\). This should be corrected in a manner similar to the `DECLARE_CCTK_ARGUMENTSX_FunctionName` macros in C\+\+.
