Special collection operators

There are two special collection operators available in Corticon Studio's Operator Vocabulary that allow us to evaluate collections for specific Conditions. These operators are based on two concepts from the predicate calculus: the universal quantifier and the existential quantifier. These operators return a result about the collection, rather than about any particular element within it. Although this is a simple idea, it is actually a very powerful capability – some decision logic cannot be expressed without these operators.
