[Rd] minor suggestion for optim documentation

   consider adding the following clause to the optim documentation describing SANN? I had to go look this up in the optim.c code for a student who is not proficient in C, and it may be simple enough to include it in the documentation. (This replaces the existing sentence that ends where the semicolon is.)

Temperatures are decreased according to the

   logarithmic cooling schedule as given in Belisle (1992, p. 890);    specifically, the temperature is set to \code{temp/(log((t-1) %/%tmax)*tmax+exp(1))},

   where \code{t} is the current iteration step.

   sincerely
     Ben Bolker
