[time-nuts] Lady Heather calendar functions

[Mark Sims]

Yes,  Lady Heather has some rather extensive calendar functions built in,  including a list of common (and not so common) holidays.  If the file heather.cal is found,  it uses that file for the holidays... you can add your own or delete some.   Otherwise it uses the built in list.   I don't think John's latest distribution has the .CAL file...  

The calendar file can handle fixed days,  days like the first/last Thursday of a given month,  and some computable religious holidays (mostly Christian, Jewish, Muslim).  Also start of the  seasons,  Chinese New Year, etc.  Even calculates the moon phase and shows it in the watch display.

It can also display dates in several different calendars (including Aztec, Mayan, Druid, Indian,  Persian,  Islamic,  Jewish,  and a bunch of others).  Also can display sidereal time.

Also has alarm clock,  egg timer,  chiming clock,  singing clock functions.  A lot of documentation is in the comments at the start of the file heather.cpp
