Need to add a scale for the TimelineView

[lukescott]

Need to add a TimelineScaleView for the TimelineView. This would probably be a fixed view with a drawRect that draws different parts of the scale depending on the scroll position. For the TimelineView itself, it would just accept any kind of UIView and keep its position fixed while scrolling and cause the scale view to redraw.

Currently don't have a need for it in my current project, so the priority for it isn't very high.

Looks like I'll be chugging away at this in my fork this week
