The following changes are planned:
1. Abandon the use of byte*3 variables for date, time and alarmtime and in
stead use 3 separate byte variables for the parts: no confusion about sequence.
2. Abandon use of 'hhmmss' and 'yymmdd' in function names and use 'time' and
'date' in stead.
3. Abandon use of suffixes '_bcd' and '_bin' in names of functions and
procedures. It should be clear from the purpose of the function or procedure if
bcd or binary notation is used.
4. Rename functions which return a relative value to rtc_get_secondofday,
rtc_get_minuteofday, rtc_get_dayofweek (etc, when more functions of such are
added).
(to be continued)
Rob.

A first version of the refactored library is committed under a temporary name:
rtcc_hw_ng.jal. The sample program 18f26j11_rtcc_hw_kbd_lcd.jal is modified for
use of the new library.
Most points of the previous 2 comments have been implemented, and the embedded
documentation is extended. The procedures and functions for the alarm facility
have been revised significantly to provide a functionality resembling regular
alarm-clocks without restrictions to make use of all possibilities of the RTCC
module.
Some more tests are needed to check if everything works as designed and all
desired functional improvements are in place before replacing the old library.

Added 2 functions for date caluculations:
- get_dayofmonth() returns number of days since first of 'this' month: 0..30
- get_dayofyear() returns number of days since 1st of Jan 'this' year: 0..365
Library seems complete and tests did not reveal problems: issue closed.
