+1.1 by Jack Christensen
+Changed data types of variables and functions:
+ o event types and indexes changed from int to int8_t.
+ o periods and durations changed from lon to unsigned long.
+ o update() and stop() functions typed as void, since they return nothing.
+ o pin numbers and pin values changed from int to uint8_t, this agrees with digitalWrite().
+ o added return values to Timer::pulse() and Timer::oscillate(uint8_t, unsigned long, uint8_t).
+ o changed test in Event::update() to use subtraction to avoid rollover issues.
+ o Updated keywords.txt file to include all functions.
+
+1.2 by Damian Philipp
+ o Added a range check to Timer::stop() to avoid memory corruption.
+ o Added constants to <Timer.h>: 
+    - NO_TIMER_AVAILABLE: Signals that while an event was to be queued, no free timer could be found.
+    - TIMER_NOT_AN_EVENT: Can be used to flag a variable that *might* contain a timer ID as
+      *not* containing a timer ID
+ o Replaced a bunch of magic numbers in <Timer.cpp> by the above constants
+ o Added several comments
+ o Added Timer::pulseImmediate(). pulseImmediate sets the pin to the specified value for the given
+   duration. After the duration, the pin is set to !value.
+   
+1.3 by Jack Christensen
+ o Added "blink2" example illustrating flashing two LEDs at different rates.
+ o 19Oct2013: This is the last v1.x release. It will continue to be available on GitHub
+   as a branch named v1.3. Future development will continue with Sandy Walsh's v2.0 which
+   can pass context (timer ID, etc.) to the callback functions.
