User-visible changes

Jittering on the probability scale seems broken and is currently only available for logit-type models.

Incorporated pkgdown website.
Added paper URLs and ORCIDs to DESCRIPTION file (#30).
Added sure vignette
incorporated autoplot methods for glm, lrm, orm, polr, vglm
autoplot() can now return multiple plots (#16).
Specifying method = "latent" now works for binomial GLMs (27).
Specifying method = "jittering" now issues a warning (at least until it has been fully tested).

New function surrogate for returning the surrogate response values used in calculating the surrogate-based residuals. The surrogate response values can be useful for checking the proportionality assumption of fitted cumulative link models, among other things.
Jittering (on both the probability scale and the response scale) is now available for fitted cumulative link models based on packages MASS, ordinal, rms, and VGAM (#18).
Added support for vector generalized additive models from the VGAM package (i.e., objects of class "vgam").
New data sets df4 and df5 for illustrating various uses of the surrogate residual for diagnostics an ordinal regression models.
