#1 Serializable classes

[Giovanni Tummarello]

Hi there, i am working on a project which uses SNARLI
neaural networks (snarli.sourceforge.net) which in turns
use jlinalg. I was able to make a neural network serialize
just fine by adding a serializable interface to the required
classes both in snarli and in jLinAlg but of course its
much better if you guys do it on your side :-)

just add "extend serializable" .. where needed and voila..
streamable. Looking forward to this. Thanks!
