+ * 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)
+ * TD - Tail of the Dragon (Cauda 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.
