/* Algorithm:
. Prepare array of N units, where N is the value of "limit" configuration setting
. Load data for the most recent units from file
If a unit with required ID doesn't exist, just add an empty unit
. Get data for the current unit
. Process data from the units and prepare an output map object:
* per time unit counters:
* DNS-queries/time-unit
* blocked/time-unit
* safebrowsing-blocked/time-unit
* parental-blocked/time-unit
If time-unit is an hour, just add values from each unit to an array.
If time-unit is a day, aggregate per-hour data into days.
* top counters:
* queries/domain
* queries/blocked-domain
* queries/client
To get these values we first sum up data for all units into a single map.
Then we get the pairs with the highest numbers (the values are sorted in descending order)
* total counters:
* DNS-queries
* blocked
* safebrowsing-blocked
* safesearch-blocked
* parental-blocked
These values are just the sum of data for all units.

// getData returns the statistics data using the following algorithm:

// 1. Prepare a slice of N units, where N is the value of "limit" configuration
// setting. Load data for the most recent units from the file. If a unit
// with required ID doesn't exist, just add an empty unit. Get data for the
// current unit.
//
// 2. Process data from the units and prepare an output map object, including
// per time unit counters (DNS queries per time-unit, blocked queries per
// time unit, etc.). If the time unit is hour, just add values from each
// unit to the slice; otherwise, the time unit is day, so aggregate per-hour
// data into days.
