F4E example runs on standard MDS+/Matlab interface

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.
