+ 	ThreadController.h - Controlls a list of Threads with different timings
+
+	Basicaly, what it does is to keep track of current Threads and run when
+	necessary.
+
+	ThreadController is an extended class of Thread, because of that,
+	it allows you to add a ThreadController inside another ThreadController...
+
+	For instructions, go to https://github.com/ivanseidel/ArduinoThread
+
+	Created by Ivan Seidel Gomes, March, 2013.
+	Released into the public domain.
