Update documentation before making Github release and adding DOI

• Add link to Github repo
• Update software/hardware instructions?
• Perhaps add note on how to cite
• Change date
• Add license
• Make Github release
• Get DOI?

new question with extra credit for either fully Python or full R implementation

new question(s) on static vs dynamic models

• idea: compare U1-U0 to u1-u0; if they don't differ much then estimating a static model should be fine too, and the inner loop tolerance should not matter much
• for the current parameter values the difference is small
• AP: try to find parameter values such that the difference is bigger (call this parameters 2)
• ask students to assess dependence of importance of inner loop tolerance on parameter values
• ask students to estimate a static model and check when this gives good estimates

\item Extend |negLogLik| (or add functions) so that it optionally takes nonparametric estimates of $\Delta U$ as inputs, computes the corresponding estimates of the entry and exit rules, and uses these estimates and the model to forwardly simulate $U_0(x,a)$ and $U_1(x,a)$, and then $\Delta U(x,a)$, for each point $(x,a)$ in the sample. As possible objectives to be minimized, both implement a weighted distance between the nonparametric estimates of $\Delta U$ and the simulated values of $\Delta U$, and minus a log pseudo-likelihood based on the choice probabilities implied by the simulated values of $\Delta U$.

incorrectly suggests that forward simulations should be rerun for each trial parameter value. We should instruct students to code up the forward simulations and value evaluation separately instead.
