/* A very basic example of how to get the network statistics from the system 
 * and diaply them. Also it adds up all the traffic to create and print out
 * a total 
 * Takes several arguments :
 * -d <number>  Takes the number of seconds to wait to get traffic sent since last call
 *              Note, this is not network traffic per second. Its the traffic since last
 *              call. If you want it traffic per second averaged over time since last call
 *              You need to divide against the time since last time this was called. The time
 *              between 2 calls is stored in systime in the network_stat_t structure.
 * -b           Display in bytes
 * -k           Display in kilobytes
 * -m           Display in megabytes
