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

// Inputs to modify below:
// numDays - number of days into the past to fetch
// eventFunnel - ordered array of events that define the completion funnel
// levelSlugs - [optional] array of levels to examine, otherwise fetch all levels
// testGroupFn - return group value from user testGroupNumber

// Include getFunnelData(), log()
