Regression Modeling Strategies

Current Goals

A non-downward compatible change will occur in the next release of the package
The survfit.formula function (seen by the user as just survfit) for obtaining nonparametric survival estimates will be replaced by the npsurv function
The purpose is to avoid conflicts with the survival package
survfit.coxph has a new id option that generalizes individual=TRUE; need to change survfit.cph and survest.cph to use that

Fix survplot so that explicitly named adjust-to values are still in subtitles. See tests/cph2.s.
Fix fit.mult.impute to average sigma^2 and then take square root, instead of averaging sigma
Implement user-added distributions in psm - see https://github.com/harrelfe/rms/issues/41
