/**
* Iteration through each element of an Array in "canonical order".
* The user obtains this by calling getIndexIterator() on an Array.
*
* Canonical order for A[i][j][k] has k varying fastest, then j, then i.
* Example: Replace array with its square:
*
*
* IndexIterator iter = A.getIndexIterator();
* while (iter.hasNext()) {
* double val = iter.getDoubleNext();
* iter.setDoubleCurrent( val * val);
* }
*
*
* Note that canonical order may not be physical order.
