/*! \p omp::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 omp::vector may vary dynamically; memory management is
 *  automatic. The elements contained in an \p omp::vector reside in memory
 *  available to the \p omp system.
 *
 *  \tparam T The element type of the \p omp::vector.
 *  \tparam Allocator The allocator type of the \p omp::vector. Defaults to \p omp::allocator.
 *
 *  \see http://www.sgi.com/tech/stl/Vector.html
 *  \see host_vector For the documentation of the complete interface which is
 *                   shared by \p omp::vector
