* @todo allow setting more curl options: PUT, POST, exit on socket receive error
* @todo verify if we do proper curl error checking for all cases (404 tested)
* @todo parse more stats from children (same format as ab does), eg. print connect times, nr. of keepalives etc...
* @todo check if all our calculation methods are the same as used by ab
* @todo add some nice graph output, as eg. abgraph does
* @todo !important add named constants for verbosity levels; review what is ouput at each level (currently used: 1 to 4)
* @todo !important add an option for a custom dir for traces/logfiles
* @todo !important raise php timeout if run() is called not from cli
* @todo !important in web mode, display a form to be filled by user that triggers the request
