/**
 * Aggregate expressions perform operations on lists of data, either directly on a list of scalars, or indirectly on a list of objects, with a reference to a property present on each object in the list.
 * 			
 * Aggregate expressions deal with missing information by excluding missing values from consideration before performing the aggregated operation. For example, in a Sum over Dose, any instance of Medication with no value for Dose would be ignored.
 * 
 * An aggregate operation performed over an empty list is defined to return null, except as noted in the documentation for each operator (Count, AllTrue, and AnyTrue are the exceptions).
 *
