Swappable Iterator Concept

A class or built-in type X models the Swappable Iterator concept if, in addition to X being Copy Constructible, the following expressions are valid and respect the stated semantics.

Swappable Iterator Requirements (in addition to Copy Constructible)
Expression Return Type Postcondition
iter_swap(a, b) void the pointed to values are exchanged
[Note: An iterator that is a model of the Readable and Writable Iterator concepts
is also a model of Swappable Iterator. --end note]
