Classes that provide the basic workbench UI support for undo and redo of operations.

## Package Specification

This package provides utilities that implement the common function for interacting with the workbench operation history. The workbench operation support provides access to the operation history used by the workbench and a context that should be used to identify operations global to the workbench. The workbench history is used to maintain all undoable operations that occur in the workbench. Standard action handlers and an associated action group are provided so that any view or editor can easily add undo/redo support that works with the workbench operations history. Specialized operation approvers can be used by clients to get user approval for unexpected conditions in the operation history.
