* @brief A specialization of vector for booleans which offers fixed time
* access to individual elements in any order.
*
* Note that vector<bool> does not actually meet the requirements for being
* a container. This is because the reference and pointer types are not
* really references and pointers to bool. See DR96 for details. @see
* vector for function documentation.
*
* @ingroup Containers
* @ingroup Sequences
*
* In some terminology a %vector can be described as a dynamic
* C-style array, it offers fast and efficient access to individual
* elements in any order and saves the user from worrying about
* memory and size allocation. Subscripting ( @c [] ) access is
* also provided as with C-style arrays.
