ScalaLab Improvements

Hi all,

I like to inform the group that ScalaLab281 includes also an
additional interface to the Scala Interpreter,
based on the ScalaInterpreterPane of Hanns Holger Rutz.

That interface can be opened from the "Swing console" top-level menu
choice.

I found that interface convenient in things like the text coloring and
completion support.

Also, the design of implicit conversions is improved to include
operations on Array[Double] and Array[Array[Double]] types.
The new design of implicit conversions is described in the
ImplicitConversionsDesignNote.html document.

I intend to submit and other such small design documents that perhaps
can open fruitful discussion for improvements.

.. also the functional aspects of my numerical classes are very weak,
and I think to improve them significantly soon.

Best Regards

Stergios
