/*
Originally, if one did a constraint on a Grid such that only
one array or map in the grid was returned, that element was
returned as a top level variable. This is incorrect because
it loses the Grid scope information.
Eventually, this behavior was changed so that such partial
grids are converted to structures where the structure name
is the grid name. This preserves the proper scoping.
However, it is still the case that some servers do the old
behavior.
The rules that most old-style servers appear to adhere to are these.
1. Asking for just a grid array or a single grid map
returns just the array not wrapped in a structure.
2. Asking for a subset of the fields (array plus map) of a grid
returns those fields wrapped in a structure.
3. However, there is an odd situation: asking for a grid array
plus any subset of maps that includes the last map in the grid
returns a malformed grid. This is clearly a bug.
For case 1, we insert a structure node so that case 1 is consistent
with case 2. Case 3 should cause an error with a malformed grid.
[Note: for some reason, this code has been difficult to get right;
I have rewritten 6 times and it probably is still not right.]
[2/25/2013 Sigh! Previous fixes have introducted another bug,
so now we fix the fix.]
Input is
(1) the root of the dds that needs to be re-gridded
(2) the full datadds tree that defines where the grids are.
(3) the projections that were used to produce (1) from (2).
