//!
//!@brief A variable-size array container with fixed capacity.
//!
//!static_vector is a sequence container like boost::container::vector with contiguous storage that can
//!change in size, along with the static allocation, low overhead, and fixed capacity of boost::array.
//!
//!A static_vector is a sequence that supports random access to elements, constant time insertion and
//!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 static_vector may vary dynamically up to a fixed capacity
//!because elements are stored within the object itself similarly to an array. However, objects are
//!initialized as they are inserted into static_vector unlike C arrays or std::array which must construct
//!all elements on instantiation. The behavior of static_vector enables the use of statically allocated
//!elements in cases with complex object lifetime requirements that would otherwise not be trivially
//!possible.
//!
//!@par Error Handling
//! Insertion beyond the capacity result in throwing std::bad_alloc() if exceptions are enabled or
//! calling throw_bad_alloc() if not enabled.
//!
//! std::out_of_range is thrown if out of bound access is performed in <code>at()</code> if exceptions are
//! enabled, throw_out_of_range() if not enabled.
//!
//!@tparam Value    The type of element that will be stored.
//!@tparam Capacity The maximum number of elements static_vector can store, fixed at compile time.
