/* CtrafStatsEntry.C: function definitions for the stats themselves
* Source/port, destination/port, amount. (timestamp gets added
* runtime during insertion in the database)
Functions:
* Constructor
* copy constructor (need it for the list)
* Destructor
* < operator - checks source then sport then destination then dport
* += operator - adds two entries -- IF THEY MATCH.
* + operator (see above)
* matches - returns true if all but amount the comparant
* asString - returns printable version of contents, for logging
purposes
* print - prints it out
* asQuery - Takes a timestamp and returns an SQL INSERT query
