//!
//!\tparam StoredSizeType An unsigned integer type. It shall be smaller than than the size
//! of the size_type deduced from `allocator_traits<A>::size_type` or the same type.
//!
//!If the maximum capacity() to be used is limited, a user can try to use 8-bit, 16-bit 
//!(e.g. in 32-bit machines), or 32-bit size types (e.g. in a 64 bit machine) to see if some
//!memory can be saved, specially for empty containers. This could potentially improve performance
//!due to better cache usage.
//!
//!Note that alignment requirements can disallow theoretical space savings. Example:
//!\c vector holds a pointer and two size types (for size and capacity), in a 32 bit machine
//!a 8 bit size type (total size: 4 byte pointer + 2 x 1 byte sizes = 6 bytes) 
//!will not save space when comparing two 16-bit size types because usually
//!a 32 bit alignment is required for vector and the size will be rounded to 8 bytes. In a 64-bit
//!machine a 16 bit size type does not usually save memory when comparing to a 32-bit size type.
//!Measure the size of the resulting container and do not assume a smaller \c stored_size
//!will always lead to a smaller sizeof(container).
//!
//!If a user tries to insert more elements than representable by \c stored_size, the container
//!will throw a length_error.
//!
//!If this option is not specified, `allocator_traits<A>::size_type` (usually std::size_t) will
//!be used to store size-related information inside the container.
