Delete scheduled Tasks

[Lakelezz]

Deleting scheduled tasks is a feature I would like to add.
It will require to change the underlying data-structure.

Hi, are you working on this?

Perhaps you could just add interfaces for into_sorted_vec and From<Vec<T>>.

Hello, dlee13!

I'm currently trying to redesign the internal structure of the scheduler.
Once that is done, this task will high likely be next :)

On another note, functions to construct a scheduler from a Vec and to get the scheduler's tasks as Vec might be useful, I will consider this while creating the new internals.
