\class Core::IEditor
\brief The IEditor is an interface for providing different editors for different file types.
Classes that implement this interface are for example the editors for
C++ files, ui-files and resource files.
Whenever a user wants to edit or create a file, the EditorManager scans all
EditorFactoryInterfaces for suitable editors. The selected EditorFactory
is then asked to create an editor, which must implement this interface.
Guidelines for implementing:
\list
\o displayName() is used as a user visible description of the document (usually filename w/o path).
\o kind() must be the same value as the kind() of the corresponding EditorFactory.
\o The changed() signal should be emitted when the modified state of the document changes
(so /bold{not} every time the document changes, but /bold{only once}).
\o If duplication is supported, you need to ensure that all duplicates
return the same file().
\endlist
