* Cleaned up label logic in Surv, made it work with interval2 (thanks:Chris Andrews)
   * Fixed bug in val.prob - wrong denominator for Brier score if obs removed for logistic calibration
   * Fixed inconsistency in predictrms where predict() for Cox models used a design matrix that was centered on medians and modes rather than means (thanks: David van Klaveren <d.vanklaveren.1@erasmusmc.nl>)
   * Added mean absolute prediction error to Rq output
   * Made pr argument passed to predab.resample more encompassing
   * Fixed logLik method for ols
   * Made contrast.rms and summary.rms automatically compute bootstrap nonparametric confidence limits if fit was run through bootcov
   * Fixed bug in Predict where conf.type='simultaneous' was being ignored if bootstrap coefficients were present
   * For plot.Predict made default gray scale shaded confidence bands darker
   * For bootcov exposed eps argument to fitters and default to lower value
   * Fixed bug in plot.pentrace regarding effective.df plotting
   * Added setPb function for pop-up progress bars for simulations; turn off using options(showprogress=FALSE) or options(showprogress='console')
   * Added progress bars for predab.resample (for validate, calibrate) and bootcov
   * Added bootBCa function
   * Added seed to bootcov object
   * Added boot.type='bca' to Predict, contrast.rms, summary.rms
   * Improved summary.rms to use t critical values if df.residual defined
   * Added simultaneous contrasts to summary.rms
   * Fixed calculation of Brier score, g, gp in lrm.fit by handling special case of computing linear predictor when there are no predictors in the model
   * Fixed bug in prModFit preventing successful latex'ing of penalized lrms
   * Removed \synopsis from two Rd files
   * Added prmodsel argument to predab.resample
   * Correct Rd files to change Design to rms
   * Restricted NAMESPACE to functions expected to be called by users
   * Improved Fortran code to use better dimensions for array declarations
   * Added the basic bootstrap for confidence limits for bootBCa, contrast, Predict, summary
   * Fixed bug in latex.pphsm, neatened pphsm code
   * Neatened code in rms.s
   * Improved code for bootstrapping ranks of variables in anova.rms help file
   * Fixed bug in Function.rms - undefined Nam[[i]] if strat.  Thanks: douglaswilkins@yahoo.com
   * Made quantreg be loaded at end of search list in Rq so it doesn't override latex generic in Hmisc
   * Improved plot.summary.rms to use blue of varying transparency instead of polygons to show confidence intervals, and to use only three confidence levels by default: 0.9 0.95 0.99
   * Changed Surv to Srv; use of Surv in fitting functions will result in lack of time labels and assumption of Day as time unit; no longer override Surv in survival
   * Changed calculation of Dxy (and c-index) to use survival package survConcordance service function when analyzing (censored) survival time; very fast
   * Changed default dxy to TRUE in validate.cph, validate.psm
   * Dxy is now negated if correlating Cox model log relative hazard with survival time
   * Removed dxy argument from validate.bj as it always computed
   * Added Dxy to standard output of cph, psm
   * Added help file for Srv
   * Removed reference to ps.slide from survplot help page
   * Changed predab.resample to allow number of intercepts from resample to resample
   * Fixed bug in Mean.cph (thanks: Komal Kapoor <komal.bitsgoa@gmail.com>)
   * Removed incl.non.slopes and non.slopes arguments from all predict methods
   * Changed all functions to expect predict(..., type='x') to not return intercept columns, and all fitting functions to not store column of ones if x=TRUE
   * Changed nomogram argument intercept to kint, used default as fit$interceptRef
   * Made bootcov behave in a special way for orm, to use linear interpolation to select a single intercept targeted at median Y
   * Revamped all of rms to never store intercepts in design matrices in fit objects and to add intercepts on demand inside predictrms
