to do this, we'd need the following:

- extend the loader with a "sum filter" argument, containing a filter
that needs to be applied before adding up entries in a dataset (e.g.
to filter out projected spending, revenue etc.)
- apply conversion to convert all datasets into a common currency,
e.g. USD (is that still the currency of choice?)
- Sum up (can be done using aggregator) and cache result (same).

Any other requirements?
