/*
Title : Actions
Author: Edward R. Gonzalez
Description: This was a little experiment of mine to mess with action binding...
Allows for non-member functions to be binded to an action, implements a functioning queue as well.
TODO: Possibly add support for member functions. Have it so that deduction of delegate typef is not required to add to queue properly (right now it does, see input procedure for example);
