[kepler-dev] Build Broken (by MatlabExpression.java?)

My bad with that. I always figured that that java compliance settings in 
eclipse meant that the code would compile under 1.4 (or maybe it does 
and i'm doing something wrong). I've modified the actor now and compiled 
it using 1.4 to make sure it works, and will commit it again later on 
today (when i'm 100% sure it wont break anything :)).

I've looked into the java interfaces that come with matlab, and as far 
as i can tell they're not much use to us.

 From what i've managed to figure out, they just allow people to write 
java classes for use inside matlab's own jvm (i.e. the classes must be 
called from inside matlab), and don't do anything when run from a 
standard jvm.

If anyone knows any different, please let me know. I'm not a big fan of 
the whole spawning additional processes to preform these tasks, and even 
less of having to parse text output to decipher the results. But for now 
i don't know of any other way of doing this.
