Choice
Chooses a value from a set of values based on conditions.
The Choice function is used to provide a value according to a condition from a list of conditions. It is similar to a collection of nested IfThenElse functions but more compact.
Any number of ChoiceValue functions are provided as arguments. Each ChoiceValue function provides a condition and value pair; the value is emitted when the first condition is satisfied.
One of the ChoiceValue functions may be marked as a default value and that value is emitted if no other condition is satisfied.
