/**
   DS1307, DS3231 and DS3232 RTCs basic library

   Really tiny library to basic RTC functionality on Arduino.

   Supported features:
 *     * SQuare Wave Generator
 *     * Fixed output pin for DS1307
 *     * RAM for DS1307 and DS3232
 *     * temperature sensor for DS3231 and DS3232
 *     * Alarms (1 and 2) for DS3231 and DS3232
 *     * Power failure check for DS3231 and DS3232

   See uEEPROMLib for EEPROM support.
