 /**
   * This class represents the interface to the MyMoney engine.
   * For historical reasons it is still called MyMoneyFile.
   * It is implemented using the singleton pattern and thus only
   * exists once for each running instance of an application.
   *
   * The instance of the MyMoneyFile object is accessed as follows:
   *
   * @code
   * MyMoneyFile *file = MyMoneyFile::instance();
   * file->anyMemberFunction();
   * @endcode
   *
   * The first line of the above code creates a unique MyMoneyFile
   * object if it is called for the first time ever. All subsequent
   * calls to this functions return a pointer to the object created
   * during the first call.
   *
   * As the MyMoneyFile object represents the business logic, a storage
   * manager must be attached to it. This mechanism allows to use different
   * access methods to store the objects. The interface to access such an
   * storage manager is defined in the class MyMoneyStorageMgr. The methods
   * attachStorage() and detachStorage() are used to attach/detach a
   * storage manager object. The following code can be used to create a
   * functional MyMoneyFile instance:
   *
   * @code
   * MyMoneyStorageMgr *storage = ....
   * MyMoneyFile *file = MyMoneyFile::instance();
   * file->attachStorage(storage);
   * @endcode
   *
   * The methods addAccount(), modifyAccount() and removeAccount() implement the
   * general account maintenance functions. The method reparentAccount() is
   * available to move an account from one superordinate account to another.
   * account() and accountList() are used to retrieve a single instance or a
   * QList of MyMoneyAccount objects.
   *
   * The methods addInstitution(), modifyInstitution() and removeInstitution()
   * implement the general institution maintenance functions. institution() and
   * institutionList() are used to retrieve a single instance or a
   * QList of MyMoneyInstitution objects.
   *
   * The methods addPayee(), modifyPayee() and removePayee()
   * implement the general payee maintenance functions.
   * payee() and payeeList() are used to retrieve a single instance or a
   * QList of MyMoneyPayee objects.
   *
   * The methods addTag(), modifyTag() and removeTag()
   * implement the general tag maintenance functions.
   * tag() and tagList() are used to retrieve a single instance or a
   * QList of MyMoneyTag objects.
   *
   * The methods addTransaction(), modifyTransaction() and removeTransaction()
   * implement the general transaction maintenance functions.
   * transaction() and transactionList() are used to retrieve
   * a single instance or a QList of MyMoneyTransaction objects.
   *
   * The methods addSecurity(), modifySecurity() and removeSecurity()
   * implement the general access to equities held in the engine.
   *
   * The methods addCurrency(), modifyCurrency() and removeCurrency()
   * implement the general access to multiple currencies held in the engine.
   * The methods baseCurrency() and setBaseCurrency() allow to retrieve/set
   * the currency selected by the user as base currency. If a currency
   * reference is empty, it will usually be interpreted as baseCurrency().
   *
   * The methods liability(), asset(), expense(), income() and equity() are
   * used to retrieve the five standard accounts. isStandardAccount()
   * checks if a given accountId references one of the or not.
   * setAccountName() is used to specify a name for the standard accounts
   * from the GUI.
   *
   * The MyMoneyFile object emits the dataChanged() signal when data
   * has been changed.
   *
   * For arbitrary values that have to be stored with the storage object
   * but are of importance to the application only, the object is derived
   * for MyMoneyKeyValueContainer which provides a container to store
   * these values indexed by an alphanumeric key.
   *
   * @exception MyMoneyException is thrown whenever an error occurs
   * while the engine code is running. The MyMoneyException:: object
   * describes the problem.
