# IPC::JSON is the mother class for all exchanged messages (using JSON).
# IPC::JSON inherited classes have a common 'type' class attribute,
# which enables to find the right IPC::JSON+ class given a TypedMessage's type.
# All transfered messages are typed messages.
# TypedMessage = u8 type (= IPC::JSON+ class type) + JSON content.
# 'JSON content' being a serialized IPC::JSON+ class.
# Conventionally, IPC::JSON+ classes have a 'handle' method to process incoming messages.
