Classes for the creation of workbench parts that integrate with the Eclipse Platform User Interface.

## Package Specification

A workbench part is a visual component within a workbench page. There are two types: view and editor, as defined by `IViewPart` and `IEditorPart`. An editor is typically used to edit or browse a document or input object. A view is typically used to navigate a hierarchy of information (like the workspace), open an editor, or display properties for the active editor. This package provides a base implementation for the definition of views and editors.
