* A helper method to ensure that a settings binary object is uptodate.
* The "uptodateness" is determined by the \a settingsBinaryUptodate parameter.
* If the binary needs updating, it is updated by reading the settings file determined
* by the \a settingsFileName parameter.
* \param settingsBinaryUptodate determines if the settings binary is uptodate or not.
* This parameter will be \c true after this method returns.
* \param settingsBinaryObjectPointer a pointer to the pointer variable of the binary to be manipulated.
* \param settingsFileName the file name of the settings file.
