Changes in the DAS and how it's combined with the DDS to make the DDX has rippled through the tests

In bes/cmdln/tests some of the tests show an odd thing. Because we eliminated hierarchy in the DAS some attributes in synthesized responses like the DDX has changed and/or gone away. This shows up in Grids. Look at these tests using COADS (a data file with Grids):

• coads_climatology.ddx2.bescmd - constrained DDX

• coads_climatology.ddx.bescmd - unconstrained DDX

These are currently tests 38 and 39 of ./besTest in bes/cmdln/tests.

The attributes for the Grid variables' maps are missing, but present in the copies of the Maps that appear as top-level variables in the unconstrained response. In the constrained response, only one Grid is present (and no top-level copies of the Maps). There is no attribute information for the SST Grid's Maps.

I think this is a bug, although there may be no solution we find acceptable given other constraints.
