+###### WORDS OF WARNING
+# This implements a simple http JSON "RPC" server for the generator
+#
+# The keyword here is simple! You do NOT want to run this open on the
+# internet. It is purely a way to get a UI for developers of the generator
+# up and running, easily without having to spin up docker or anything else.
+#
+# More specifically this is not intented to be the RPC server that we will
+# offer to the outside world. This is just a quick-dirty test bed for RPCs
+# + the thing needed to provide the UI.
