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. */
