ExitCompass: statistics about Fast Exits

For the Exit Reimbursement Program, we need the following:

• collect aggregate bandwidth of exit relays per family and country (parse consensus/descriptors using stem), together with relay contact info

• calculate amount of compensation (in USD) per family

• webinterface to display that, a history of these values and a total aggregate per month

• generate monthly reports and send a summary to moritz (+ tor-reports?), and detailed reports to families
