-Implementations of itertools functions for Python versions that don't
-have iterators.
-
-These implement the functions by creating the entire list, not returning
-it element-by-element as the real itertools functions do.  This means
-that early Python versions won't get the performance benefit of using
-the itertools, but we can still use them so the later Python versions
-do get the advantages of using iterators.
-
-Because we return the entire list, we intentionally do not implement the
-itertools functions that "return" infinitely-long lists: the count(),
-cycle() and repeat() functions.  Other functions below have remained
-unimplemented simply because they aren't being used (yet) and it wasn't
-obvious how to do it.  Or, conversely, we only implemented those functions
-that *were* easy to implement (mostly because the Python documentation
-contained examples of equivalent code).
-
-Note that these do not have independent unit tests, so it's possible
-that there are bugs.
