81   1) CNH pointed out that grid interpolation needs to be handled   1) NAMING -- We should (as much as possible) try to name variables so
82        that they are in agreement with the CF naming conventions.
83    
84     2) UNITS -- as with the names we need to follow conventions
85    
86     3) AM described her "diags" (or "myDiags" or "mDiags") interface
87        which should use MNC for output.  The data storage idea is similar
88        to the MNC tables-of-indicies approach but also includes one huge
89        double-precision "accumulator" to hold all the temporary values
90        (eg. partial sums for averages, current max/mins):

92          vname ( ni )
93          vlen  ( ni )
94          vind  ( ni ) ------+
