Cross-Validation: http://emr.cs.iit.edu/home/reingold/calendar-book/Calendrica.html
3.10: May 2010 Tibetan, Zoroastrian added, Date.from() modified, DateFmFix kind argument, Long Count added to ABCalWidget, altDate eliminated
fractional fixed dates eliminated except for DateFmFix/fixFmDate and Gregorian conversions
3.00: Apr 2010 toHTML methods for Date,CalendarEvent,CalendarEventList,CalendarSeason; merged Salutation & LiturgicalSalutation; ABCalWidget location input
2.17: Dec 2008 ABCalWidget function, DateFmFix function
2.16: Jun 2008 Mayan Long Count and Hindu Kali Yuga day count added, elevation corrections to sunrise/set using topocoding.com
2.15: Jun 2008 sgn & clockMod functions added, ccMod eliminated. Bahai calendar uses Bahai dates. Liturgical time intervals can straddle midnight.
Consolidated Salutation functions. Seasons can overlap. CC-like Easter & qibla functions. Corrected shela & birkath ha-hama dates. dateLocale global object
2.13: Aug 2007 try/catch blocks added for GeoIP functions, making MaxMind script optional.
2.12: May 2007 Clock object for Liturgical Times, Solar Time calculations from NOAA, GeoIP from MaxMind.
2.02: Apr 2007 Bahai and Coptic calendars, fractional fixed (R.D.) dates, use of Date.getTime().
2.00: Jan 2006 Calendar object. Julian Calendar for Orthodox Holidays, CC-like version of from() & Hebrew Holiday adjustments.
1.00: ??? 2003 Initial version: Hebrew, Islamic and combined Western Secular-Liturgical calendars */
