I have implemented TOpenHighLowCloseSeries based on
the Wikipedia description:
http://en.wikipedia.org/wiki/Open-high-low-close_chart
See "OHLC" page in the multidemo since r29890.

Please test.

Also, the wikipedia entry indicates that lines might have different color
based on the upward/downward proce movement.
Do you need this feature?
