102   3) AM described her "diags" (or "myDiags" or "mDiags") interface   3) CNH pointed out that grid interpolation needs to be handled
     which should use MNC for output.  The data storage idea is similar  
     to the MNC tables-of-indicies approach but also includes one huge  
     double-precision "accumulator" to hold all the temporary values  
     (eg. partial sums for averages, current max/mins):  
   
       vname ( ni )  
       vlen  ( ni )  
       vind  ( ni ) ------+

  5) From the group meeting on 2004/01/21, we need to define  
     "sub-grids" corresponding to:

     And write a convenience wrapper so that users can write variables  
     using just two function calls.  JMC and I worked out the
