CustomExpressionContext

```
public class CustomExpressionContext
extends ExpressionContext
```
This class is an extension of the ExpressionContext class, tailored to deal with Expressions that contain FixedFactors and ConsumptionFactor s. It is used by the ExpressionOasisDistributionPowerModelCalculator and the ExpressionOasisResourcePowerModelCalculator to handle DeclarativePowerModelSpecifications.
The peculiarity of a measured factor is that while it is denoted by a variable within an expression, it might be composed of several values at simulation-time. For example, a measured factor outletConsumption may refer to all PowerConsumingResources that are supplied by a PowerDistributionUnit. Thus, variables that represent measured factors are polymorphic in some way, but it cannot be determined beforehand whether they are composite variables or not.
Moreover, this class also serves as a facade to all other non-public classes in this package.
