Analyse/Validate problems solved:
1) Enumerations within a class were not added as class. Now they are
added as internal class.
2) Dependencies to inner classes (including enum) of an outer class were
not reported as violations (with fast searching by means of the
dependencyFromToHashMap.
3) Viewing code after selecting a dependency/violation to a inner
class/enum did not give a result. Reason why DependencyDTO is extended
with fromClassPath and toClassPath.
