Hello everybody!

I am a bit new to Corona but i am working on a game template. Below you can find the class i wrote to handle sequential animations (function calls). It's really easy but i think it will be helpful for somebody here.
My idea is to integrate it with TransitionManager somehow, but still havent stated with that, if somebody has any ideas about it i will be glad to here them.
PS: I think methods like stopTransitions and pauseTransitions should be implemented here.

Any feedback or improvements will be appreciated!
