CRAN update v1.3.1
Updated vignette to reflect breaking changes to the prais package api in which the function prais.winsten became prais_winsten. Minor changes in DESCRIPTION file to content.
Also, bumped R dependency up to R (>= 3.2.0) to bring this package inline with the maximum dependency of its dependent packages (prais).
Updated vignette to add new graphs through chapter 7. Also, removed tidy = TRUE markdown chunk parameters as breaking changes appear to have been made, which now require the installation of a separate package.
Removed chapter 17 examples for now, as glm(formula, family = poisson, cata=crime1) is outputting an error which requires deeper exploration.
Update bibliography pages with current packages.
