-/* DebounceInt Library */
-/* This class enables debouncing a GPIO interrupt from a specific MBED pin            */
-/* It does so by using the InterruptMask library to temporarily mask the interrupt    */
-/* from the specified pin for a user specified delay specified in us. After the delay */
-/* time has passed the interrupt is unmasked (reenabled) and any pending interrupts   */
-/* also cleared. The library gives you the flexibiity to debounce on either the       */
-/* rising or falling edge interrupts.                                                 */
-// Usage:
-// Declare a DebounceInt object with a valid mbed pin (p5-p30 except p19 and p20) as 
-// an argument. Within your interrupt service routine call the appropriate debounce
-// method debouncePinRise or debouncePinFall. 
-// Requires the InterruptMask library available at: https://mbed.org/users/nleoni/code/InterruptMask/
