ReconcilerBase is a base struct from which all reconcilers can be derived from. By doing so your reconcilers will also inherit a set of utility functions To inherit from reconciler just build your finalizer this way: 

type MyReconciler struct {
  util.ReconcilerBase
  ... other optional fields ...
}
