These core changes also apply to this moduleEXPANDCOLLAPSE
Refactored Axis.update to reuse the elements and animate into new position, rather than destroying and rebuilding.
Added a className to chart.title and chart.subtitle, so styling to these elements can be applied by custom classes.
Extended the axis linkedTo option to accept another axis’ id, in addition to its index.
