int frenchtojd ( int month, int day, int year)
Converts a date from the French Republican Calendar to a Julian
Day Count.
These routines only convert dates in years 1 through 14
(Gregorian dates 22 September 1792 through 22 September
1806). This more than covers the period when the calendar was in
use.
