/*! \p cpp::vector is a container that supports random access to elements,
 *  constant time removal of elements at the end, and linear time insertion
 *  and removal of elements at the beginning or in the middle. The number of
 *  elements in a \p cpp::vector may vary dynamically; memory management is
 *  automatic. The elements contained in a \p cpp::vector reside in memory
 *  available to the \p cpp system.
 *
 *  \tparam T The element type of the \p cpp::vector.
 *  \tparam Allocator The allocator type of the \p cpp::vector. Defaults to \p cpp::allocator.
 *
 *  \see http://www.sgi.com/tech/stl/Vector.html

 *                   shared by \p cpp::vector
