/*

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...

Created by Ivan Seidel Gomes, March, 2013.

Released into the public domain.
