[jdebacker]

@jdebacker . I don't understand the Travis CI error messages for why this is not passing.

[jdebacker]

@rickecon This branch isn't up to date with the master. It's still a work in progress. I'll sync and then be moving forward with dynamic firms soon. I've got the theory down, but still testing some functions dealing with different business tax systems on the simpler code over in the OG textbook repo.
