description:
Made UFLObject a new-style class (object),
and added __slots__ property to most of the classes.
This is partly an optimization that removes the
__dict__ instance from all objects, saving memory,
but most importantly at this point it will ensure
that no additional variables are added to these
objects, giving errors if 'foo.newvar=1' is attempted.
It also documents which member variables a class
has without having to read through constructor
logic.

Added __str__ implementations most places for
pretty printing, these could be improved.
