// A tiny class to do reporting for us. We report interesting user actions

// or declining the warning.
//
// Each report has a subject and data. Current reports are:
//
// subject         data     meaning
// --------------------------------
// phishnavaway    url      the user navigated away from a phishy page
// phishdecline    url      the user declined our warning
// phishaccept     url      the user accepted our warning
// phishblhit      url      the user loaded a phishing page
//
// We only send reports in advanced protection mode, and even then we
// strip cookies from the request before sending it.
