/*
* 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.
