+### Feature
+
+- A new language `com.mbeddr.mpsutil.collections` was added that adds support for a set type `nset` that use nodes as the values of the set. Equivalence of nodes is checked structurally. The hash code calculation is done for all properties and children and the first level of references. The runtime solution also contains a more general class `EquivalenceHashSet` to implement hashsets with arbitrary `equals` and `hashcode` methods.
