Returns the average, the maximum and the minimum kilometers traveled per trip by trackers for a given company or group, grouped by vehicle type and dates.

This endpoint returns statistical information about the kilometers (average, maximum and minimum)
traveled per trip by trackers for a given company or group grouped by the vehicle type and dates.
The dates can be time periods from days to years across weeks, months and quarters.
The call must include either the company_oid or the group_oid as your identifier
and also the step in which the dates are going to be grouped by.
Optionally, the call can include the following parameters:

• start_date and end_date. These parameters specify the time period of interest, i.e. only trips that fall in between these dates will be listed.
  If the end_date is omitted, the list will include all the trips from the start_date until now.
  If both dates are omitted, the list will include the trips of the last seven days.
