spduration 0.16.0 (2017-04-11)

separationplot.spdur -> sepplot. separationplot is a standalone function so change the spdur version to a simple wrapper.
Cleaned up NAMESPACE. Moved stats to imported package in description and removed all associated explicit namespace generic imports.
Added package vignette.
Added file init.c with calls to R_registerRoutines() and R_useDynamicSymbols(); also use .registration=TRUE in useDynLib in NAMESPACE. R-devel (and R 3.4.0 in the future) R CMD check issues a NOTE for registration of routines, this is to avoid that note.
Updated DESCRIPTION and added references.

spduration 0.15.1 (2016-05-12)

Fixes bug in summary.spdur that would return wrong estimates for log(alpha).
Better column names for summary and xtable methods.
Fixes test error after testthat update.

Added accessor methods for terms, model.matrix, coef, and vcov.
Added fitted and residuals methods.
Fixes issue #17, which led to errors in summary.spdur when called on a model with factor variables or without intercept terms.
Fixes an issue with the hazard rate plot confidence intervals (plot_hazard(ci = TRUE)), where CIs coud be wrong because coefficients were sampled by equation rather than using the full variance covariance matrix.

Added Belkin & Schofer 2003 coup data in data(bscoup), see ?bscoup.
Replaced plot_hazard1 and plot_hazard2 with plot_hazard, added support for loglog models, and other internal streamlining of plotting code.
Partial fix for summarizing and printing results for models without intercept term.
Removed documentation and export for several internal functions.
