+There are basicaly, three Classes included in this Library:

 - `Thread class`: This is the basic class, witch contains methods to set and run callbacks,
   check if the Thread should be runned, and also creates a unique ThreadID on the instantiation.
 
 - `ThreadController class`: Responsable for "holding" multiple Threads. Can also be called
   as "a group of Threads", and is used to perform run in every Thread ONLY when needed.
 
+- `StaticThreadController class`: Slighly faster and smaller version of `ThreadController`.
+  It works similar to `ThreadController`, but once constructed it can't add or remove threads to run.
