A recursive template is a template that is defined in terms of itself.
Consider three classes X, Y, and Z. X is inner to Y, and Y is inner to Z.
The variable %topContainerCode% is defined to retrieve the value of the parent container of a class.
The value of the template is the following:
.if (%isInner%) %ContainerClassifier.topContainerCode% .else %Code% .endif
If the class is inner to another class, %topContainerCode% is applied to the container class of the current class (%ContainerClassifier.topContainerCode%).
If the class is not an inner class, the code of the class is generated.
