Code Integrator

This is the core of the "glue" generators that Semantix developed for
the European research project ASSERT. It has been enhanced in the
context of Data Modelling and Data Modelling Tuning projects,
and continuous to evolve over the course of other projects.

This code starts by reading the AADL specification of the system.
It then generates the runtime bridge-code that will map the message
data structures from those generated by the Semantix Certified ASN.1
compiler to/from those generated by the modeling tool used to
functionally model the APLC subsystem (e.g. SCADE, ObjectGeode,
Matlab/Simulink, C, Ada, etc).

The code generation is done via user-visible (and editable) backends.

There are three kinds of backends:

1. Synchronous backends
=======================

For these, the working logic is:

for each subprogram implementation
    Load B mapper
    call OnStartup
    for each subprogram param
        Call OnBasic/OnSequence/OnEnumerated etc
    call OnShutdown

That is, there is OnStartup/OnInteger/OnSequence/.../OnShutdown cycle
done PER EACH SUBPROGRAM.

2. Asynchronous backends
========================

Asynchronous backends are only generating standalone encoders and decoders
(they are not doing this per sp.param).

The working logic is therefore different

OnStartup called ONCE for each async backend in use (used by this system's PIs)
Via the asynchronous.py, after visiting all params and collecting them,
for each asn.1 type that is actually used (at least once) as a param:
    Call Encoder and Decoder
Call OnShutdown ONCE for each async backend in use (used by this system's PIs)

3. Special backends
===================

GUI, Python, (VHDL?), etc...

These have custom requirements, so each one is handled by specific AADL2GLUEC
code. As it is now, the pattern follows that of the synchronous backends,
but with an extra call to OnFinal at the end.
