Detailed Description

TaskSequence is a container for sequentially executing tasks, and it is a task by itself. It will raise completed event, only if it is started through its start() method, and all of the tasks in the list are also completed.

The tasks container is arranged as a LinkedList. We iterate to the next task, only when the previous task is completed.

TaskSequence provides functionallity to edit the TasksList when the TaskSequence is already started. The only limitation is that the currently executing task can't be deleted - an attempt to do this will raise an exception.
