MagmaTesterLoader-cmm.20

[Chris Muller]

I have just posted the improvements based on "Magma on 3.7 report" from
Bert.  This 1.0 release now minimizes the impact of cleaning up the
'objects' Dictionary that was causing some performance issues.  It also
restores use of MaWeakValueDictionary which is many times faster with
large dictionary's than a plan WeakValueDictionary.

MagmaServerLoader and MagmaClientLoader were also udpated, of course.

There's also a bug fix related to specifying depths for variables
defined in superclasses.

Enjoy.
