Added: clickEvent event - Called when the user clicks on a person box.

Added: renderBoxContentEvent event - Before the GetOrgChart can be rendered, each box in the control must be bound to a record in the data source. The renderBoxContentEvent event is raised when a data (represented by a GetOrgChart object) is bound to data in the GetOrgChart control. This enables you to provide an event-handling method that performs a custom routine, such as modifying the values of the data bound to the box or modifying the box html, whenever this event occurs.

Added: scale option - The scale factor determines what fraction of the entire scale is visible at one time.
