Hooked up Engagement Index with API

https://jira.ets.berkeley.edu/jira/browse/CYB-82

PR crucial for today's meeting

Hooked up @richcreationsrc Engagement Index with DataCulture's API
DataCultures can query it's DB and bring relevant information to Engagement Index
Could you show me on my machine how to do this? I've been trying but I can't get it to work
