/**
  * @page backend The structure of the backend
  * <p>
  * The backend implementation for Sword is called CSwordBackend, the classes we use
  * to work with keys are called CSwordVerseKey and CSwordLDKey, both are derived from
  * the class CSwordKey.
  * The CSwordKey derived classes used for Sword do also inherit the classes
  * VerseKey (CSwordVerseKey)
  * and SWKey (CSwordLDKey).
  * </p>
  * <p>
  * The classes used to handle all module based stuff are derived from CSwordModuleInfo.
  * The module classes are: CSwordModuleInfo (for Sword modules),
  * CSwordBibleModuleInfo (for bibles), CSwordCommentaryModuleInfo (for commentaries) and
  * CSwordLexiconModuleInfo (for lexicons).
  * Have a look at the class documentation of the mentioned classes to learn how the
  * structure of them looks like and which class inherits which other class.
  * </p>
  * <p>
  * The first objects which should be created in the application is the backend
  * (for Sword the class is called CSwordBackend).
  * Then create all the different module classes for the correct Sword modules.
  * Have a look at
  * BibleTime::initBackend() to see how it's done in BibleTime.@br
  * Later you can work with them for example by using the CSwordKey and
  * CSwordModuleInfo derived class.
  * </p>

/**
  * @page frontend The structure of the frontend
  *
  * <p>
  * The frontend contains the classes which interact with the user. For example the
  * display windows, the searchdialog or the other parts.
  * </p><p>
  * The display windows which provide functionality are CBibleReadWindow for
  * Bibles, CBookReadWindow for books, CCommentaryReadWindow for commentaries and CLexiconReadWindow for
  * lexicon and dictionaries. CHTMLWriteWindow and CPlainWriteWindows are used for editing the Personal Commentary.
  * </p><p>
  *
  * The class CDisplayWindow is the class that various views with in the windows are derived.
  * </p><p>
  *
  * Another important part of the frontend are the keychoosers.
  * They provide an interface to choose a key of a module.
  * The interface for different module types is different.
  * The base class is CKeyChooser which is the factory for the derived classes.
  * Use the function CKeyChooser::createInstance to get the correct
  * keychooser implementation for the desired module.<br/>
  * </p><p>
  * Some major toolbar widgets are CKeyChooser and BtDisplaySettingsButton.
  * </p>

/** @mainpage BibleTime - Source Code Documentation
 * BibleTime main page.
 * <p>This is the source code documentation of BibleTime, a Bible study tool.
 * <p>
 * The main class of BibleTime is called @ref BibleTime, which is the main window
 * and initializes all important parts at startup.
 * </p><p>
 * BibleTime is divided in two major parts, the backend and the frontend.
 * The text display windows belong to the @ref frontend.
 * The backend is mainly a wrapper around Sword's classes to use Qt functionality
 * to allow easy access to it's functionality and to have it in a (more or less :)
 * object oriented structure.</p>
 * <p>
 *       - Introduction to the frontend: @ref frontend<br/>
 *       - Introduction to the backend: @ref backend<br/>

/** BibleTime's main class.

 * This is the main class of BibleTime! This class creates the GUI, the QAction objects

 * the creation of widgets into initView and the connect(...) calls into initConnections.
 * Reading from a config file on creation time should go into readSettings(), saving into
