The refactoring of the Task system is nearly complete. Now there are multiple types of tasks including `StringTask` and `MapTask`. Each task type is responsible for running itself and processing its own result. This makes it much easier for people to create new task types. Also, the map and parallel function support has been completely refactored and improved. This includes a map and parallel function implementation for the task controller as well as a @parallel decorator.
