Hey @claire98han & @maestapereira - thanks for all the work on this, we are super close!

As well as the open PR (#68), I updated the comment above to untick the sim_spiketrain_prob and sim_spiketrain_binom functions - the listed PR was for the warning that got added, but unless I'm missing the tests are still ToDo. Once those are added, we are finished this task!

Hi @TomDonoghue, you're right - thanks for correcting it!
I wrote the functions but didn't add them to a branch and didn't open PRs. I will do that right away:)
