/*@Doc:
The {\tt r_Dir_Decompose} class is used to specify a decomposition on
an n-dimensional cube (for use in {\tt r_Dir_Tiling}). For instance, to
specify a tiling restriction on a dimension with the form: [0, 2, 4, 5],
the following code would apply:
r_Dir_Decompose decomp;
decomp << 0 << 2 << 4 << 5;
Note that the first and the last elements input into the object must be
the origin and limit of that dimension or else a cross-section of the domain
will occur (as if the elements outside the specification wouldn't mind).
If one dimension is considered to be a prefered access direction, then
the r_Dir_Decompose should be empty, this is, no restriction should be
entered.
