The longer the time countdown on the progress bar, the less frequently the screen is refreshed, which results in less power consumption when running the Meditation, Relaxation, Power Nap and Focus Timer applications.

/** ProgressTimer connects Timer's features with UI representation.
|
|
* The Timer's features consists of:
|
|
* 1) counting time down,
|
|
* 2) ability to perform action (via onIntervalCallback) periodically on reaching an interval
|
|
* 3) ability to perform action (via onFinishedCallback) on reaching countdown end.
|
|
* The UI representation consist of:
|
|
* 1) ability to present time left on attached Text
|
|
* 2) ability to present timer's progress on attached class realising Progress interface.
