WHAT THIS OBJECT REPRESENTS
This object represents an arbitrary precision unsigned integer
the following operators are supported:
operator +
operator +=
operator -
operator -=
operator *
operator *=
operator /
operator /=
operator %
operator %=
operator ==
operator <
operator =
operator << (for writing to ostreams)
operator >> (for reading from istreams)
operator++ // pre increment
operator++(int) // post increment
operator-- // pre decrement
operator--(int) // post decrement
the other comparison operators(>, !=, <=, and >=) are
available and come from the templates in dlib::relational_operators
THREAD SAFETY
bigint may be reference counted so it is very unthread safe.
