    // Get/SetStartStop - the timeline times at which this object is
    //      active. Groups and Tracks have start times of zero.
    // FixTimes - used by the render engine. Rounds the input times
    //      to the nearest FPS of the parent Group, for use in setting
    //      up the big switch.
    // GetSubObject - get the sub-object which is associated with this
    //      timeline object. Each timeline object can carry around a
    //      pointer to 'something else'. For our Render Engine, this is
    //      a pointer to a filter that gets put into a graph.

    //      to force this. If you don't want it to do this, don't call
    //      this function.

    //      instead give it a GUID and see if this works instead. The
    //      sub-object will attempt to be instantiated when 'necessary'
    //      which is really when it's asked for with GetSubObject./
    //      !!! a better way to do this perhaps?
    // GetSubObjectLoaded - ask if the sub-object pointer is set
    // Get/SetTimelineType - return the major type which is stored here,
    //      used by the API user and the render engine.
    // Get/SetTimelineSubType - see above
    // Get/SetUserID - get and set a number, any number
    // GetGenID - every created object has a unique number to it. Used
    //      by the render engine.
    // Get/SetUserName - a storable name, for users of the API
    // Get/SetPropertySetter - the object that will set properties for this
    //      object (it will support IPropertySetter and it is created by 
    //      CPropertySetter)
    // Get/SetUserData - gets the persistant data used by the user of
    //      the API.
    // Get/SetMuted - set whether this object should be active or not.
    //      Setting a parent of other objects off also turns off the
    //      sub-objects.
    // Get/SetLocked - set whether you can edit this object or not.
    //      Note: the timeline doesn't enforce this, it just stores
    //      a value for convenience.
    // Get/SetDirtyRange - 
    // RemoveAll - remove this object, and if in the tree already, all it's
    //        sub objects, including children
