After resolving Issue 15, we should create, for each model, simulation code calculating the difference-in-differences. The naming convention should be to use ```dd``` as the last two letters of the simulation function name.

Note that ```dd``` functions will need to have two different cf objects as inputs, each with specified ```x``` and ```xpre```.
