* GEOMANCY WATCH FACE
*
* A simple and straightforward watch face for the ancient Eastern geomantic divination system
* of I Ching and the western system of "Geomancy". It is an optional addition to the Toss Up
* Face.
*
* The LIGHT button toggles between the two systems of geomancy.
*
* The ALARM button casts an I Ching hexagram or Geomantic figure based on drawing virtual
* stalks from the True Random Number Generator in the Sensor Watch.
*
* The figures are flipped 90 degrees clockwise, so the left side is the bottom and the
* right side the top.
*
* LONG PRESSING ALARM toggles the display of the King Wen sequence index for the cast I Ching
* Hexagram (https://en.wikipedia.org/wiki/King_Wen_sequence )or the abbreviated name for the
* cast Geomantic Figure:
*
* GF - Greater Fortune (Fortuna Major)
* LF - Lesser Fortune (Fortuna Minor)
* PO - Populus
* VI - Via
* AL - Albus
* CO - Conjunctio
* PA - Puella
* AM - Amissio
* PR - Puer
* RU - Rubeus
* AQ - Acquisitio
* LA - Laetitia
* TR - Tristitia
* CA - Carcer
* HD - Head of the Dragon (Caput Draconis)

* TOSS UP FACE
* ============
*
* Playful watch face for games of chance or divination using coins or dice.
*
* LIGHT switches between Coins and Dice mode
*
* COINS
* =====
*
* ALARM tosses a coin. If it lands on heads it gets sorted to the left side of the
* display, if it lands on tails then sorted to the right side.
*
* LONG PRESSING ALARM adds up to 5 more coins to the toss for more nuance in the decision
* making (e.g. three heads vs two tails could be read as "yes, but with serious doubts").
*
* LONG PRESSING LIGHT flips through additional style for the coins from the default Ө/O
* to H/T (heads/tails), Y/N (yes/no), E/Ǝ, C/Ↄ
*
* LONG PRESSING ALARM on the "Coins" title page resets to one coin.
* LONG PRESSING LIGHT on the "Coins" title page resets the style to Ө/O
*
* DICE
* ====
*
* ALARM rolls a six sided dice.
*
* LONG PRESSING ALARM adds up to 2 more dice to the roll.
*
* LONG PRESSING LIGHT flips through other available polyhedral dice types with less or more
* than the default 6 sides. The options are D2, D4, D6, D8, D10, D12, D20, D24, D30, D32, D36,
* D48, and a hypothetical D99.
*
* When more than one dice is used for a roll this changes only the last added dice. (see Note
* below)
*
* LONG PRESSING ALARM on the "Dice" title page resets to one dice.
* LONG PRESSING LIGHT on the "Dice" title page resets the dice to D6.
*
* Please Note: If you need let's say a D8, D12, and D20 for your rolls then the procedure to
* set this up would be as follows: from the default screen where you can roll the one D6 dice
* you would LONG PRESS LIGHT a few times to change the D6 to a D8, then LONG PRESS ALARM to add
* a second dice, LONG PRESS LIGHT again until the second dice changes to D12, then LONG PRESS
* ALARM to add the third dice and LONG PRESS LIGHT again a few times until it becomes a D20.
