// foreshadowsLevels A/B Results
// Test started 2015-01-29, ended 2015-02-26
// Fixed some particle problems on 2015-02-02
// Fixed more particle problems in old browsers on 2015-02-19
// Final results: tests showed no difference in completion rates, but slight drops in level start rates for non-Chrome browsers, so we stopped doing it outside of Chrome.

// Usage:
// mongo <address>:<port>/<database> <script file> -u <username> -p <password>
