/*!
 * This class manages all editors and their positioning in tabWidgets.
 *
 * It maintains the knowledge of the currentEditor() and the currentTabWidget().
 * Also, it sends appropriate signals to the editors and tabWidgets and provides
 * signals to hook to these changes.
 *
 * Currently this class serves two purposes:
 *
 * 1) It maintains an abstract order of editors. Editors can be grouped (currently
 *    implemented as tabs in tabWidgets). The groups are ordered and the editors
 *    within a group are ordered, thus providing a complete order of all editors.
 *    The main purpose of this class it to provide an interface to this order, which
 *    can be used in the main program without having to know details on the actual
 *    organization of groups.
 *
 * 2) It contains all tabWidgets and thus editors providing a simple horizontal or
 *    vertical layout of the tab groups (there are currently 2 groups).
 *    This purpose is secondary and mainly implemented for an easier transition from
 *    the single tabGroup to more complex editor layouts. It may be changed in the
 *    future and will probably move to a separate class. The public interface of the
 *    class should depend on this as little as possible.

/*! \class EditorChangeProxy
 *
 * This class handles changes of the currentEditor
 *
 * There are two ways that can lead to emission of the signal currentEditorChanged():
 *
 * 1) First, other components can connect to the slot editorChange(). These signals are
 * just propagated, except if the EditorChangeProxy is blocked.
 *
 * 2) Second, one can block() the propagation of changes and release() later on. At release(),
 * the proxy checks if the currentEditor has changed from the one at blocking. If so, the
 * currentEditorChanged() signal is emitted.
 * Use the block/release mechanism to perform complex actions that consist of multiple
 * editor changes (potentially even with inconsistent intermediate states) during which
 * you don't want to emit currentEditorChanged().
 * You have to make sure that you release the block if and only if you acquired it. Therefore,
 * blocking should always use this pattern:
 *
 *     bool b = changes->block();
 *     ...
 *     if (b) changes->release();
 *
 * If you have return statements in the intermediate code, be sure to place the release command
 * also before every return.
