2018 post mortem

[titaniumbones]

Please use this comment to list things that could have been improved in this assignment in 2018. I'll try to fix them for the next time I run the class:

• more comprehensive "ignore" list for git, including especially .DS_Store files and utils/allstudents.js. Commits that included these files led to lots of problems that had to be manually resolved (addressed in d09f2e0)
• decide definitively what to do with package-lock.json. probably best to commit it to the package, so that npm install generates the same set of node modules on every machine. However, there's a danger that different npm versions will require different package versions... so, a conundrum. In any case, either commit or ignore.
• better instructions for navigating the filesystem. This was a big issue for people
• teach some basic command-line shortcuts, like up and down errors, C-s and C-r for search, etc.
