- * RANDONAUT FACE
- * ==============
- *
- * Randonauting is a way to turn the world around you into an adventure and get the user outside
- * of their day-to-day routine by using a random number generator to derive a coordinate to journey
- * to. In Randonauts lore so-called "Blind Spots" are places you cannot reach methodologically. They
- * may exist in your own backyard for your whole life and you will never even notice them, because
- * you simply have no reason to go to that exact place or look in its direction. Since the very
- * limitations of our behavioral algorithms are the reason for the existence of blindspots, they
- * can only be found using a randomizer.
- *
- * This watch face generates a random location based on the watch's location and a set radius using
- * the official Randonautica Blind Spot algorithm.
- *
- * The ALARM button starts the random location generation and then automatically displays the found
- * Blind Spot.
- *
- * By pressing ALARM again the user can flip through different pieces of information about the Blind
- * Spot: Distance (DI), Bearing Degree (BE), Latitude degrees and decimal digits (LA), Longitude
- * degrees and decimal digits (LO).
- *
- * Pressing LIGHT switches between generating a new blind spot ("Rando") and displaying the info of
- * the last generated one ("Point").
- *
- * LONG PRESSING LIGHT toggles setup mode. Here pressing LIGHT switches between setting the desired
- * radius (RA) and setting the random number generator (RNG) for generating the blind spot.
- *
- * ALARM changes the values respectively:
- *
- * - The radius can be set in 500 meter steps between 1000 and 10,000 meters
- *
- * - The RNG can be set to "true" which utilizes the SAML22J's internal True Random Number Generator
- * - Setting it to "psudo" will use the pseudorandom number generation algorithm arc4random
- * - Setting it to "chance" will randomly chose either of the RNGs for each generation (default)
- *
- * LONG PRESSING ALARM toggles DATA mode in which the currently generated Blind Spot coordinate can
- * be written to the <place.loc> file on the watch (press ALARM) and set as active high precision
- * location used by other watch faces. It does not overwrite the low precision location information
- * in the watch register commonly used for astronomical watch faces.

- * PLACE FACE
- * ==========
- *
- * Based on and expanded from the Sunrise/Sunset face. Outsourced the location setting functionality to
- * its own face. Also serves as a converter between different coordinate notation formats.
- *
- * With the LIGHT button each place coordinate can be shown and edited in 4 different display modes:
- *
- * 1) Decimal Latitude and Longitude (WGS84) up to 5 decimal points
- * 2) Latitude and Longitude (WGS84) in traditional DD°MM'SS" notation
- * 3) Ten digit Open Location Code (aka. PlusCode) format
- * 4) Ten digit Geohash format
- *
- * Using the ALARM button the user can flip through 2 pages of coordinate info to see the first and
- * second sets of digits.
- *
- * (please also refer to the notes on precision below)
- *
- * Editing Mode
- * ============
- *
- * A LONG PRESS of the LIGHT button toggles editing mode for each of the selected notations.
- *
- * In this mode LIGHT moves the cursor and ALARM changes the letter cycling through the available
- * alphabet or numbers.
- *
- * When OLC or Geohash display are edited, Digit Info mode is activated. It serves as a workaround
- * for the limitation of how ambiguously alphanumeric characters are displayed on the main seven segment
- * digits of the watch face ( S or 5, I or 1, U or W?).
- *
- * The selected letter is also shown in the much easier to read alphanumeric 8 segment weekday digit above.
- * In addition the '24H' indicator is active when the selected digit represents a number and the 'PM'
- * indicator for a letter.
- *
- * A LONG PRESS of LIGHT saves the changes.
- *
- * Coordinates are read or stored to both the traditional internal location register and a file on
- * the LFS file system ("place.loc"). By default the Watch Face loads the coordinates from file
- * when activated. If no file is present, the coordinates are loaded from the register.
- * (please also see the notes on precision below)
- *
- * Auxiliary Mode: Digit Info
- * ==========================
- *
- * A LONG PRESS of the ALARM button toggles Digit Info mode when OLC or Geohash display is active.
- * (LAP indicator is on) It is a means of being able to see the detailed Digit Info as described above
- * but without the risk of accidentally editing any of digits.
- *
- * Both ALARM and LIGHT buttons can be used to flip through the letters.
- *
- * Notes on Coordinate Precision
- * =============================
- *
- * The common WGS84 Latitude and Longitude degrees naturally do not represent meters in distance
- * on the ground. 1° Longitude on the equatorial line equals a width of 111.32 kilometers, but
- * at 40° latitude further North or South it is approximately 85 kilometers wide. The closer to
- * the poles the narrower (and more precise) the latitude degrees get.
- *
- * The Sensor Watch's traditional 16bit location register only stores latitudes and longitudes
- * with two decimal points. That equals a longitudal precision of 36 arc seconds, or ~1111 meters
- * at the equator - precise enough for astronomical calculations, but not if you want to store the
- * location of let's say a building.
- *
- * Hence we propose the <place.loc> file that serves the same purpose, but with a precision of
- * five decimal digits. That equals 0.04 arc seconds or 1.11 meters at the equator.
- *
- * Please also note that the different notations of this watch face also have varying magnitudes
- * of precision:
- *
- * | Format | Notation | Precision at Equator | Precision at 67° N/S |
- * | ------------------ | ---------------------- | -------------------- | -------------------- |
- * | 2d. Decimal LatLon | 29.98, 31.13 | 1111.320 m | 435.125 m |
- * | 5d. Decimal LatLon | 29.97916, 31.13417 | 1.111 m | 0.435 m |
- * | DMS LatLon | N 29°58′45″, E 31°8′3″ | 30.833 m | 12.083 m |
- * | Open Location Code | 7GXHX4HM+MM | 13.875 m | 13.875 m |
- * | Geohash | stq4s3x1qu | 1.189 m | 0.596 m |
- *
- * Since all notations are internally converted into degrees with 5 decimal points, expect some
- * rounding errors when editing or loading the coordinates in other notation formats.
- *
