Now the weibull model has an automatic choice of starting values, fixing a bug that prevented
fitting the weibull function in most cases in the last version. Also, the log EC50 is reported
as estimated with nlm from the fitted weibull model. Because of the important changes, mainly
in naming the different models which leads to incompatibility with the old drfit syntax,
I am increasing the minor version number to 0.04 with this release.
