/**
  \file SFBErrors.h Definitions of the failed assertion 'blink codes'.  This file defines the known
  "die blinking codes" that may occur.

  When any of a large class of programming errors is detected, the SFB will stop normal operation
  and repeatedly display a 'blink code' that may help in determining what went wrong.

  The blink code is preceded by blinking of the face LED's in a NS-EW-NS-EW-NS sequence, followed by
  0 to 6 red flashes, then 0 to 6 green flashes, and finally 0 to 6 blue flashes; then the entire
  sequence repeats.

  If an error flashes, say, 1 red, then 3 green, then 5 blue, that corresponds to \code
  BLINK_CODE(1,3,5) \endcode Searching for that blink code in SFBErrors.h then reveals that an
  E_API_REFLEX_FULL error has occurred.

  Notes:

  - All codes of the form BLINK_MAP(0,X,Y) -- i.e., with no RED flashes -- are reserved for
    sketch use!

  - The range of blinks per color is 0..7, but only 0..6 are used so far; 7 in any position is
    reserved for expansion

  - Normally once a blink code occurs, it will blink indefinitely, until the SFB is reset.  But if
    the #RF_OKAY_NEW_GUY reflex flag is set, then after a small number of blink code displays the SFB
    will attempt to reboot automatically.
