Disaggregated primitive SDEs

[JPercival]

Needs additional information:

Measures can be defined to include SupplementalDataElements that me either Resources or primitive values. In some cases the primitive values should be aggregated (for example, the number of males across the entire population) for demographic purposes. In other cases we do not want to aggregate the values because they don't have any meaning when aggregated (for example, days since last appointment)

[JPercival]

• Create an extension (or something) to indicate which SDEs should or should not be aggregated
• Update the evaluator to respect those extensions

[JPercival]

Something like this maybe:

extension: supplementalDataType=Individual
extension: supplementalDataType=Population

extension: supplementalDataAggregate=False

Coordinate with Bryn once this one is started to discuss how the extension should look

I don't think we should be using the term "aggregate" here, SDEs function as accumulators at the population level. Apologies for missing this in the previous discussion.
