docstring: Processes number of unique visitors for the given period
  
  This is the only Period metric (ie. week/month/year/range) that we process from the logs directly,
  since unique visitors cannot be summed like other metrics.
  
  @param array Metrics Ids for which to aggregates count of values
  @return array of metrics, where the key is metricid and the value is the metric value
