// This watch face is just for testing; if we want to build accelerometer support, it will likely have to be part of Movement itself.
// The watch face only logs events when it is on screen and not in low energy mode, so you should set LE mode to Never when using it
// and make it the first watch face in the list (so we come back to it from other modes).
// On an interrupt, it flashes the Signal icon, and displays the axis or axes that were over the threshold.
// The main display contains, from left to right, the number of interrupt events that were detected in each of the last three minutes.
// Pressing the alarm button enters the log mode, where the main display shows the number of interrupts detected in each of the last
// 24 hours (the hour is shown in the top right digit and AM/PM indicator, if the clock is set to 12 hour mode)
