Hi Folks,
Final commit simply adds license headers to all XML files e.g.

    modified:   stack/rest/src/test/resources/usergrid-rest-deploy-context.xml

Once these ones are committed we only have
javascript
x-c
x-java-source
x-sh

Then we can roll a release candidate... I think.

i merged this request, also noticed the e2e tests weren't working

[shawnfeldman]

also under running and deploying https://github.com/apache/incubator-usergrid/blob/master/portal/README.md#running-deploying-or-developing

you can run the e2e tests by running "./build.sh e2e", this will validate that nothing is broken

I see a lot of reformatting in this pull request and that makes it a little difficult to see exactly what changed. The changes seem to reformat from tabs to 2-space indent, which might be fine -- I'm not sure what our convention is for JS code.

Any front-end guys want to weigh-in on this PR?
