+    eoESMutationInit. Proxy class that is used for initializing the mutation
+    operator. It provides an interface between eoEsMutate and the abstract
+    parameterLoader. It also provides the names for the parameters in this 
+    class as virtual protected member functions.
+    
+    If you have more than a single ES in a project that need different
+    names in the configuration files, you might consider overriding this class 
+    to change the names.
