Add comments in big code block
First look for configuration.visibleDivider, then visibleIndex
Call showDivider or showIndex on initial render
Move subscribing to visibleDivider and visibleIndex outside of calibrateHeight, as it can lead to multiple subscriptions
Split updateIndexRange into calculateStartIndex and updateIndexRange
On initial render, look at configuration.visibleIndex. Render tiles around that index and scroll to it
Add tests for applyining initial visibleIndex when data source smaller than eviction threshold
Wrap tests for data source larger than eviction threshold
Re-indent tests
renderViewPort - call showIndex before updateIndexRange, so viewport.top will be exactly as expected
Add tests for applying initial visible index when having more items than the eviction threshold
Merge pull request #14 from mwoc/master

Make knockout.list scroll to initially visible divider or index
Also showcase having something after a list, in scrollable example
Alter tests for scrollable so there's both an offset element above and below the list, update expectations
Add scroll element relative horizontal/vertical tile position helper methods
Simplify calculateStartIndex by using scroll element-relative calculations
Alter updateIndexRange so it will skip viewport indexes if not the entire viewport is used by current list
Remove a TODO which is now done
Add scrollToTop helper
Use scrollToTop, scrollToBottom instead of implicit methods
