// METHOD:
// void Country::Update( RTIfedTime& newTime )

// PURPOSE:
// Update the state of the Country's population based on
// the new time value. The deltaTime is calculated based
// on the last time the Country object was updated and
// the newTime passed in. The deltaTime is multiplied by
// the growth rate and current population to determine the
// number of births in the deltaTime. The population is
// increased by the number of births.
//
// RETURN VALUES:
// None.
//
// HISTORY:
// 1) Created 11/6/96
// 2) Updated to RTI 1.3 3/26/98
