- update cross-reference link for CRAN compatibility
 
- Added pkgdown, moved ChangeLog to NEWS.md
 
- Refactor code to align with lintr standards, adding Hugo Gruson as
contributor.
 
- update vignette to Rmd, removal of plot method for cd.fit
object.
 
- minor modifications to fix improper call to 
class() and
other new NOTES. 
- merged hackout3 branch to support new distributions
 
- minor modifications to address NAMESPACE issues.
 
- added Azman/Lessler contributions: MCMC estimation functions,
ability to fit Weibull and Gamma distributions, and bootstrap confidence
intervals.
 
- changed code to eliminate NOTE message in R CMD CHECK.
 
- added get.obs.type() function to easily generate observation types
for data set up in doubly interval censored format.
 
- added functions for simulation precision of estimated percentiles
from coarse incubation period datasets.
 
- added documentation for datafiles.
 
- added functions (with documentation) for estimating a univariate
distribution with an arbitrary mixture of doubly interval-censored,
single interval-censored and exact observations using a maximum
likelihood approach.
 
- added functions (with documentation) for estimating the relative
case fatality ratio. Currently only tested on situations with two groups
of interest, i.e. two levels of covariate J.
