st: new packages -xbrcspline- and -ftocci- on SSC

[Nicola Orsini <Nicola.Orsini@ki.se>]

Thanks to Kit Baum,

two new packages -xbrcspline- and -ftocci- are now available for  
download from SSC.

-xbrcspline- displays differences in predicted responses after  
estimating a restricted cubic spline model.

-ftocci-  back calculates the conventional confidence intervals from  
the floated confidence
          intervals or from the floated standard errors of a set of  
relative risks.

Best regards,
Nicola
