Title: Implement task model

* Builder now is easier to use by taking advantage of move assignment operator
from the Task directly.

For example,

```
Task task = Task::Builder::description("Hello World")
.deadline(tomorrow());
```
* Creating a task with empty description throws an exception.

* General improvement.
