Installs hooks (see prolog_trace_interception/4)
into the system that redirect tracing information to a GUI front-end
providing structured access to variable bindings, graphical overview of
the stack and highlighting of relevant source code.
This predicate installs the above-mentioned hooks that redirect tracing
to the window-based environment. No window appears. The debugger window
appears as actual tracing is started through trace/0,
by hitting a spy point defined by spy/1
or a break point defined using the PceEmacs command Prolog/Break
at (Control-c b).
