+/*@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.
