+# Note, this is an OOP pattern for this that I find slightly more natural
+# The problem is we want the client xapp to be able to call methods defined in the RMRXapp
+# Another exactly equivelent way would have been to use Closures like
+# def consume(summary, sbuf):
+#    xapp.rts()
+# xapp = RMRXapp(consume)
+# However, the subclass looks slightly more natural. Open to the alternative.
