[Ola Hodne Titlestad <olati@xxxxxxxxxx>]

When it comes to e.g. population or staffing numbers it makes sense to sum
on orgunit and average on time, so don't think we are planning to change
the default behaviour here.

That said, from the use case Jason described it probably makes sense to
also support average on orgunit dimension, but then it would have to be
implemented as an additional aggregation operator, and not replacing the
current one.

Also note that the analytics web api opens up for any kind of aggregation
if you want to develop  a custom report or data visualisation that needs
aggregation logic not directly supported by DHIS 2.
