the class PreferencesMenu method loadPreferences.

/**
 * Loads a saved table preferences JSON file and updates the table format
 * (displayed column/column order and sort order) to match the values found.
 * <p/>
 * This method will place a lock on the table to prevent any updates to the
 * preferences whilst this load is happening.
 * <p/>
 * This method will start work on the JavaFX thread to update certain parts
 * of the table like column visibility. Once the method returns it is
 * recommended that the current thread waits for that work to complete
 * before initiating any other actions.
