+ some cosmetics

Standard Java based MDS+/Matlab interface tested
with the F4E example. Previously SPC mdsipmex based
interfaced was used, not suitable for a public
accessible example. NB: we do not know if
the Java interface is as optimized as the mdsipmex
one (i.e. if it uses a connection stack for example),
for for SPC usage we have to revert back to the
mdsipmex version or implement a connection
stack/ corrnection order in the SCDclass* objects.

Removed a warning
Added a try-catch
Added some fprintf for clarity

printMARTe2config now doesn't require any mds connection
to produce its output and can take a model filter
optional parameter as the actualize

modified SCDclass objects to enable actualization
of single models

matlab MDS+ classes fixed for correctly
handling optional parameters,
f4e example included, simulink debug
passes after expcode setup.

This reverts commit 15196ccb.

F4E expcode and example added, passes the sl debug,
data actualiztion, simulation and codegen
to be tested
