+/*
+	StaticThreadController.h - Controlls a list of Threads with different timings
+
+	Basicaly, what it does is to keep track of current Threads and run when
+	necessary.
+
+	StaticThreadController is an extended class of Thread, because of that,
+	it allows you to add a StaticThreadController inside another kind of ThreadController...
+
+	It works exact as ThreadController except you can't add or remove treads dynamically.
+
+	Created by Alex Eremin, September, 2016.
+	Released into the public domain.
