OK - Thanks.
Robert is the expert on this feature, so no doubt he
will correct me when I go wrong.

As I understand it, the container mechanism is built around the idea
of "types" of container (or "container factories"). So you might have
one type of container that's built using simple linked lists,
one that's built using binary trees, one that's built using hash
buckets, and one that returns entries at random.
The behaviour of each of these container types is constant, regardless
of the data that's actually held by a given example of it. So when you
construct a new data store, you'll specify which of the defined container
types ("linked_list", "table_container", "nonexistent_hash" or "random")
you want to use, and the library will return an appropriate container,
with the relevant lookup routines, etc.
The global variable 'containers' is used to hold the list of these
"container factories" - so that an appropriate example can be returned
when required.
Is that reasonably accurate, Robert?
