TaskTracker (Hive Query Language 4.0.0 API)

```
public class TaskTracker
extends Object
```
This class will be responsible to track how many tasks have been created, organization of tasks such that after the number of tasks for next execution are created we create a dependency collection task(DCT) -> another bootstrap task, and then add DCT as dependent to all existing tasks that are created so the cycle can continue.

addTask
```
public void addTask(Task<?> task)
```
this method is used to identify all the tasks in a graph. the graph however might get created in a disjoint fashion, in which case we can just update the number of tasks using the "update" method.
