ammend previous - still trying to figure out help for two functions for same class
last small fix before redoing the weekly in a more efficient way.
reviewing weekly functions -
for funtions that SET (rather than use) the classes, it is impossible not to duplicate the functions.

to keep consistency, all syndromic were relabelled to syndromicD, and now creation of syndromicW reviewed and retested.
reviewing weekly functions - raw to syndromic also need to be duplicated

former functions changed to raw_to_syndromicD

two functions created for weekly data (D-->W and W-->W)
weekly - general functions reviewed

plus small changes in all prevous files to avoid so much duplication in the help menu
small corrections missed before
weekly revision - retro_summary
redefining functions setDate, setBaseline, etc, because since they define generic and method on the same code, if keeping the same code for D and W, one replaces the other
weekly review - clean baseline functions
error on raw to syndromic that was causing problems in the sequence when the last/first week of the year is shared between two years
