Inspired by Fitbit's Flare clockface.

The flare is created by heartrate, based on your resting and maximum heartrate.

Basically, the higher your heartrate => more and brighter 'dots'.

The clock's color updates every time your heartrate changes - there are 10 colours, from blue (low heartrate) to red (high heartrate).

In the center, the time is displayed in 24-hour format (only hours and minutes) and there are 2 'arc' indicators for goal progress and battery life.

Permissions required:

- 'Activity' for the goal 'arc' and to draw the 'initial' flare.

- 'User Profile' for resting and maximum heart rate.

- 'Sleep' to turn off heart rate monitoring while asleep.

- 'Heart Rate' to display and update the flare and color of the clock face.

Changelog:

-v1.1: found out the clock doesn't do anything when display is off. Switched to the activity history to display the flare.

-v1.0: initial release - finally got the flare I wanted.
