/// This is the master trainer object and does all the heavy work.
///
/// The training object gets the already filtered "new key pressed" events from the main window
/// and processes them. It manages the level and line adjustments, starts, pauses and restarts
/// a training, updates the widgets and and and...
/// <p>
/// Whether in training or not the user may switch levels using the level change buttons (if enabled)
/// or change the lecture. The slot levelUp() or levelDown() is called and the trainer is switching
/// levels accordingly.
/// <p>
/// There is always a current training session. On a typical program start the training session is paused.
/// When a training session is paused the timer is stopped and the program waits for the next keypress
/// of the user and then the timer is restarted. Note that the Pause button (Pause action) is enabled/disabled from
/// the main KTouch class.
/// <p>
/// When the user starts a new training session or quits the program the current level/session
/// statistics data will be added to the user statistics and the stats will be cleared. If a new
/// level is started (during a session), only the level stats are stored and cleared, the session
/// statistics is kept. The only member functions, that add statistics data to the users statistics are
/// therefore storeTrainingStatistics() (for level and session stats) and statsChangeLevel() (stores only
/// level stats).
/// <p>
/// The trainer keeps record of the current level and session stats seperately and
/// stores them in the m_levelStats and m_sessionStats member variables. However, the word count is only

/// and the statusbar of the main window). In this member function also the word count of the current line
