EpiModel v1.1.2

### NEW FEATURES
* Implement `control.dcm` option `dede`, which if true allows for delayed
  differential equations to be passed into a new model solved with `dcm`.
* New option for `netdx` to simulate static diagnostics from an ERGM, rather
  than the temporal diagnostics (still the default). This will help better
  diagnose poor dynamic model fit when using the edges dissolution approximation
  (#175).
* Plot option added for `netdx`, with the `method` parameter, to plot boxplots of
  the simulations against the target statistics. The default is still the line
  plots (#191).
* Additional summary elements may now be plotted with `netdx` objects, similar
  to epidemic data plots: mean lines and quantile bands. Additional arguments
  added to allow toggling of these along with individual simulation lines and
  target lines.
* Print method for `netdx` is updated, along with a new statistic for the percent
  deviation between the simulation means and target statistics (#192).
* Added other epidemiological outcomes saved in user-defined modules to print
  output with `print.netsim` (#183).
* New function `get_sims` will subset and extract entire simulations from `netsim`
  objects with multiple simulations. A vector of simulation numbers may be
  specified, or if set as "mean", the simulation with the infected prevalence
  closest to the means across all simulations will be chosen.

### BUG FIXES
* Object elements saved in stochastic network models with the `save.other`
  parameter in `control.net` may now be merged with `merge.netsim` (#185).
* Quantile band is displayed in `plot` for ICMs and network models when the `y`
  argument is specified (#188).

### OTHER
* Package `deSolve` moved from import to depend (#194).
