///	\par Description
///		ICMP (Internet Control Message Protocol) has many functions on the
///		internet, including the handling of ECHO (ping) requests, relaying
///		network route status, passing connection status messages, etc.
///
///		This library currently handles only ICMP ECHO requests (ping), but
///		may be expanded to include other useful ICMP operations as needed.
