gen_server without gen_server

[Ulf Wiger (AL/EAB)]

In the Design Principles document:

http://erlang.se/doc/doc-5.4.12/doc/design_principles/spec_proc.html#6.2

plain_fsm in jungerl has a support library with 
callbacks for the system messages.

If you've started a process with one of the plain_fsm
start functions, you can call 
plain_fsm:handle_system_msg(Req, From, State, fun/1)

where the last argument is your continuation fun,
getting the possibly updated state as the argument.

This might be a handy solution if you don't care
to do anything special with the system messages.

(I have an improved plain_fsm - not yet released.
If you want to take it for a spin, let me know.)
