Classes:
1-->ThreadPool : Implements a pool of threads available to Scheduler. Has a task queue which threads lookup for tasks
2-->Scheduler : Maintains a Threadpool. Allows adding tasks for execution. Main scheduler runs in a thread separate
from the launcher.
3-->Task : An encapsulation for the callable object, its start time and its frequency. Scheduler allows these to be scheduled.
4-->Results : Class implementing DB interface and in-memory buffers for results of Tasks.

two tasks to write results of aforementioned tasks into DB. Tests scheduler functions in various ways.
