示例1: computeNetworkRangeFromAdressAndNetmask
/**
* \brief Compute the first and the last address of a network.
* That is usefull, for instance, to compute the "real" network address (the first address)
* or the broadcast address of the network
*
* @param $address (see \ref parameterType) the address of the network
* @param $netmask (see \ref parameterType) its netmask
* @param $firstAddress (see \ref parameterType - in/out)
* the first address (ie real address of the network)
* @param $lastAddress (see \ref parameterType - in/out)
* the lastAddress of the network
* (ie. : the broadcast address) (default NULL)
* @param $excludeBroadcastAndNetwork boolean exclude broadcast and network address from the
* result (false by default)
