Metaclass for tracing.

    Classes defined using this metaclass have an automatic tracing
    feature -- by setting the __trace_output__ instance (or class)
    variable to a file object, trace messages about all calls are
    written to the file.  The trace formatting can be changed by
    defining a suitable __trace_call__ method.
