/** @file option_editor.h
* @brief Base class for option editing dialog boxes.
*
* Code to provided the basis for dialogs which allow the user to edit options
* from an ARDOUR::Configuration class.
*
* The idea is that we have an OptionEditor class which is the dialog box.
* This is essentially a GTK Notebook. OptionEditorComponent objects can
* then be added to the OptionEditor, and these components are arranged on
* the pages of the Notebook. There is also an OptionEditorComponent hierarchy
* here, providing things like boolean and combobox option components.
*
* It is intended that OptionEditor be subclassed to implement a particular
* options dialog.
