Decrement operators

== Synopses

Declared in `<bslstl_bidirectionaliterator.h>`

Decrement the specified `iter` to the previous element. Return the previous value of `iter`. The behavior is undefined if, on entry, `iter` has the same value as an iterator to the start of the underlying sequence.

Move the specified `iter` to the previous element in the tree and return the value of `iter` prior to this call. The behavior is undefined unless the iterator refers to the past‐the‐end or the non‐leftmost element in the tree.
