* It's at the moment identical to the 1D test. That will change with the next commit.

* Also include namespaceNew and namespaceDelete in cdi.h.

* This should complete the separation of serial and parallel parts
  of the library.

* This was never a fault because the underlying type match assumption was
  true for all platforms used/tested.

* Library headers should always use angle brackets unless an override is
  provided by the package.

* Also replace calls of xwarning with Warning.

* Also reduce debugging output correspondingly.

* This way arguments can be formatted more flexibly and some unneeded
  white-space can be omitted.
* This also fixes some trailing whitespace issues.

* This also adds separate documentation, header, Fortran wrappers and
  pkg-config file for the cdi-pio part of the library
