// MetricsHandler

// Let the page contents record UMA actions. Only use when you can't do it from
// C++. For example, we currently use it to let the NTP log the position of the
// Most Visited or Bookmark the user clicked on, as we don't get that
// information through RequestOpenURL. You will need to update the metrics
// dashboard with the action names you use, as our processor won't catch that
// information (treat it as RecordComputedMetrics)
