- Added the create_subchart method to Chart. - Added the SubChart class. - Added an inner_width and inner_height parameter to Chart. - The time_scale method can now disable the time scale completely. Bugs: - Fixed a bug which prevented markers from being placed on charts with a timescale less than a day.
