No, I've never seen a C dynamically allocated multidimensional array
that wasn't implemented as an array of pointers.  For a two dimensional
array, each pointer in the array of pointers points to a row of the array.
Higher dimensions are implementes as pointers_to_pointers_to_....
the number of indirect levels is one less than the number of dimensions.

- This is _NOT_ 'like any other array'.
