Detailed Description

A middle-layer class that can be inherited from to gain modify rights to a RelAlgDag class. This provides a way to access private members of the RelAlgDag class without dirtying its public interface with non-const accessors that may only apply for very specific classes. Only classes/structs that inherit from this middle-layer class will have modify rights.
