Version 1.0
------------------------------------------------------------------------------
* Model parameterization for all model classes has been substantially revised
to improve organization and ability for expansion. Whereas previous models
required input of parameters directly into the main functions (now: dcm, icm,
and netsim), now the parameters are input into three parameter-processing
functions: param, init, and control. The param function sets the core
epidemic parameters, the init function sets the initial conditions, and the
control function specifies other model settings. These functions are
class-specific, so each function has a .dcm, .icm, or .net suffix.
* Modeling functions have been renamed for clarity and consistency:
- dcm is now used for deterministic compartmental models (replaces epiDCM)
- icm is now used for stochastic individual contact models (replaces epiICM)
- netest is now used for network model estimation (replaces epiNet.est)
- netsim is now used for network model simulation (replaces epiNet.simTrans)
* Network models with independence between epidemic/demographic processes and
network structures (independent models) were previously first simulated with
epiNet.simNet, and then those pre-simulated networks were input to
epiNet.simTrans. Now the network model simulation is all handled within the
simulation function, netsim.
* Network model diagnostics have been moved from within the network estimation
process (netest) to their own function: netdx. The parameter names for running,
printing, and plotting the results of these diagnostics have been updated for
consistency. See ?netdx and related functions.
* Internal model functions have been significantly revised to improve efficiency.
* The dcm function can handle model functions, parameter sets, and initial
conditions of arbitrary complexity. See the HTML vignette on this topic at:
http://statnet.org/EpiModel/vignette/NewDCMs.html
* Moved the package vignettes external to the package to reduce package size and
build time. They are now available at the EpiModel homepage at:

INITIAL RELEASE
* The EpiModel package provides functions for building, solving, and
plotting mathematical models of infectious disease.
* See the main package help function ?EpiModel-package, and the EpiModel tutorials
online at http://statnet.org/trac/wiki/EpiModel to get started.
