Detailed Description

Stores the result of the surragate expression as if this expression were a variable, but defers to the root expression for questions of deriviatives and which variables are active (this is not a real variable).

If you don't want to consider any of the variables to be active in a SurrogateVariableExpression, then do not set the root_expression_ for the SurrogateVariableExpression. This allows non-expressions (e.g. the EntityFuncs) to still contribute to the FITNESS without having to correspond to a particular state.
