* Interface for a model and expression transformation.<br>
*
* Implementing classes provide a combined model and expression transformation, allowing the calculation
* of a (potentially simpler) expression in the transformed model to calculate the result of the
* original expression in the original model.<br>
*
* The general idea is the following sequence of calls:<br>
*
* {@code ModelExpressionTransformation t = ...;}<br>
* {@code StateValues resultTransformed = check t.getTransformedExpression() in t.getTransformedModel()}<br>
* {@code StateValues result = t.projectToOriginalModel(resultTransformed);}
