\class TextEditor::PlainTextEditor
\brief The PlainTextEditor class is a text editor implementation that adds highlighting
by using the Kate text highlighting definitions, and some basic auto indentation.
It is the default editor for text files used by \QC, if no other editor implementation
matches the MIME type. The corresponding document is implemented in PlainTextDocument,
the corresponding widget is implemented in PlainTextEditorWidget.
