Detailed Description
This class augments a recipe with a set of VPValues defined by the recipe.
It allows recipes to define zero, one or multiple VPValues. A VPDef owns the VPValues it defines and is responsible for deleting its defined values. Single-value VPDefs that also inherit from VPValue must make sure to inherit from VPDef before VPValue.

An enumeration for keeping track of the concrete subclass of VPRecipeBase that is actually instantiated.
Values of this enumeration are kept in the SubclassID field of the VPRecipeBase objects. They are used for concrete type identification.
