00032 // Interface to the Grid ctor class. Grids contain a single array (the `main'
00033 // array) of dimension N and N single dimension arrays (map arrays). For any
00034 // dimension n of the main array, the size of the nth map array must match
00035 // the size of the main array's nth dimension. Grids are used to map
00036 // non-integer scales to multidimensional point data.
