Not Thread-Safe

Cool idea!

However, I see it's implied that tasks should only be enqueued on the main thread (or a single-thread in general). But I think that it should be written explicitly.

I'm aware that tasks can execute code in different threads; I specifically mean enqueuing new tasks via queue.push should all happen from a single-thread (.e.g main thread).

I implemented this library while exploring how to handle concurrency in Swift, it is kind of an experiment, and I'm not sure if it is safe to push tasks to queue from different threads or not, but generally I think it is safe, queues are implemented as singleton objects (identified by queue name) and pushing tasks to them from different threads shouldn't -in my opinion- cause any harm. Meanwhile, I'll write a test case to cover this scenario to make sure it works as expected.
That's for sure an important point to consider, Thanks for your input @ahmedk92 , I'll keep you posted when I'm done with the tests.
