Edit details:

This editable organizational chart sample was derived from Org Chart Editor and adds support for "assistant" nodes that are laid out by a custom TreeLayout below the side of the parent node and above the regular child nodes.

Whether or not a node is considered to be an "assistant" node is determined by the `isAssistant` property of the node data. The user can modify this data property via an additional context menu command.

Assistant employees may themselves be bosses of their own employees. All of a boss's reports may be assistants.
