Changed the terminology from EC50 to ED50 reflecting that the package is meant
for dose-response analysis in general and not only for concentration-response analysis. This is the first revision that has been prepared with the knowledge of the existence of the drc package for dose-response curve analysis. git-svn-id: http://kriemhild.uft.uni-bremen.de/svn/drfit@48 d1b72e20-2ee0-0310-a1c4-ad5adbbefcdc
