Scenario Management
During a simulation run, calculators in a model are run with given values for control variables to produce a set of outputs.
An instance is a value for a variable.
All variables must have at least one instance.
Variables can have multiple instances.
For a simulation run, variables use one and only one instance
Saved collection of instances is a scenario
Instances do not have to be used in any scenario
Worksheet reflects the current set of instances being used
