 These functions all exist in the Arduino environment as well as the
 SFB environment, so they will be familiar to Arduino users.  The SFB
 versions of these function have very similar behaviors to their
 Arduino namesakes, although there are some necessary differences to
 accomodate the additional features (e.g., packet handling) provided
 by the SFB core software.


  - \ref delay Pass some time -- for example, between turning-on and
    turning-off an LED, so that the light can be seen.  When #delay is
    called from a sketch #loop method, it allows packet and alarm
    handlers to be invoked.
  - \ref delayMicroseconds Really \e waste some time -- with
    interrupts disabled and \e nothing else happening.
  - \ref digitalRead Read the state of a digital pin
  - \ref digitalWrite Write the state of a digital output pin
  - \ref pinMode Set a digital pin's 'mode' to INPUT or OUTPUT (or, as
    SFB-extensions, to "REFLEX_MODE" or "HW_MODE").
  - \ref millis Access the number of milliseconds (thousands of a
    second) of uptime.  
  - \ref micros Access the number of microseconds (millionths of a
    second) of uptime
  - \ref randomSeed(u32 seed)
  - \ref random(u32 max)
  - \ref random(int min, int max)
