Add function example to first_steps example

It'll be used in documentation to show how to create function in
Beremiz.
These classes are intended for use server-side.
e.g. in a django view.py :
from pyjs.jsonrpc.django import JSONService, jsonremote
jsonservice = JSONRPCService()
@jsonremote(jsonservice)
def test(request, echo_param):
return "echoing the param back: %s" % echo_param
