/**
 * @brief EFL layout widget abstract.
 *
 * A "layout" in the context of EFL is an object which interfaces with the
 * internal layout engine. Layouts are created using the EDC language, and any
 * widget which implements this abstract must have a corresponding theme group
 * to load in order to graphically display anything.
 *
 * Theme groups for EFL widgets must be versioned. This means having a
 * "version" <tt>data.item</tt> key in the theme group for the widget. If
 * the loaded theme group for a widget has version info which is lower than the
 * currently-running EFL version, a warning will be printed to notify the user
 * that new features may be available. If the loaded theme group for a widget
 * has no version info, an error will be generated. If the loaded theme group
 * for a widget has a version that is newer than the currently-running EFL
 * version, a critical error will be printed to notify the user that the theme
 * may not be compatible.
