    1.5     13 Jan 2011 - Made the isr() protected and made the class a friend of Ticker.
                          Read the previous state and store when the sample frequency is
                          set so that initial assert_deassert_held() isn't called at startup.
                              
    1.4     13 Jan 2011 - Added an extra overloaded constructor that allows
                          the DigitalIn PinMode to be passed when the the class
                          is declared. So mode() isn't really needed but is left
                          in for completeness.
    
    1.3     13 Jan 2011 - Updated some doxygen comments.

    1.2     13 Jan 2011 - Added ChangeLog.h file.

    1.1     13 Jan 2011 - Fixed some typos.

    1.0     13 Jan 2011 - Initial release.
