Includes `rmarkdown` as dependency

rmarkdown now needs to be explicitly marked as a dependency in the Suggests section of DESCRIPTION. This release makes this change as well as a few minor documentation changes.

Version 1.0.3

Bug fixes, including: changes to unit tests to allow for a tolerance when comparing floating point values in unit tests and adding LazyData: true to DESCRIPTION to remove warning from r-devel.

v1.0.2 release

Hotfix to suppress warnings in tests created by change in sample() behaviour in upcoming R 3.6.0

v1.0.1 release

Minor documentation changes. From commit a967231)

v1.0.0

Major overhaul to the API with non-backwards compatible changes. The primary change is that both the incidence and survival models are now specifiable, in contrast to the previous version which forced a homogeneous Poisson process incidence model and a Weibull survival model that uses age and sex as covariates. These models are retained as defaults, but the user can provide custom objects for both these processes, as documented in the User Guide.

A number of small basic functions mostly relating to diagnostics have been removed to condense the API.

See the User Guide vignette for examples of the new parameterisation of prevalence and general documentation.
