Wraps an integral type with overflow detection.

/* implementation-defined */ T,
OverflowPolicy EP = safe_int_throw_policy>
class safe_int;This class wraps any integral type and models all requirements for mp-units representation types (RealScalar, MagnitudeScalable, etc.). Every arithmetic operation checks for overflow and delegates to the ErrorPolicy::on_overflow() handler on detection.
