    This class takes care of details of the trace facility;
    a derived class should implement user interaction.
    The standard debugger class (pdb.Pdb) is an example.

    The optional skip argument must be an iterable of glob-style
    module name patterns.  The debugger will not step into frames
    that originate in a module that matches one of these patterns.
    Whether a frame is considered to originate in a certain module
    is determined by the __name__ in the frame globals.

aODispatch a trace function for debugged frames based on the event.

        This function is installed as the trace function for debugged
        frames. Its return value is the new trace function, which is
        usually itself. The default implementation decides how to
        dispatch a frame, depending on the type of event (passed in as a
        string) that is about to be executed.

        The event can be one of the following:
            line: A new line of code is going to be executed.
            call: A function is about to be called or another code block
                  is entered.
            return: A function or other code block is about to return.
            exception: An exception has occurred.
            c_call: A C function is about to be called.
            c_return: A C function has returned.
            c_exception: A C function has raised an exception.

        For the Python events, specialized functions (see the dispatch_*()
        methods) are called.  For the C events, no action is taken.

        The arg parameter depends on the previous event.

    Implements temporary breakpoints, ignore counts, disabling and
    (re)-enabling, and conditionals.

    Breakpoints are indexed by number through bpbynumber and by
    the (file, line) tuple using bplist.  The former points to a
    single instance of class Breakpoint.  The latter points to a
    list of such instances since there may be more than one
    breakpoint per line.

    When creating a breakpoint, its associated filename should be
    in canonical form.  If funcname is defined, a breakpoint hit will be
    counted when the first line of that function is executed.  A
    conditional breakpoint always counts a hit.
