Controllers

* We can use the Stopwatch class to time the execution of our program.
* This commit implements this experimentally for the partition to
  colored dot execution path.
* This is considered a work in progress and should NOT be merged into
  master.
* A proper implementation would likely involve some overseeing structure
  in ConversionManager for the execution methods to hook into and
  provide their timing
* The goal is to design this independent from the frontend so an
  interface to the frontend must also be provided.
