Added a stand-in search route

I wanted to see if I understood how the pieces fit together well enough
to make a route, add fields, etc.
Added ability to make groups

But it's broken, can't interface properly with mongo. Sad 403 error.
Merge branch 'Add-/search' into Development
User can now create a group. Bugs fixed: 'numbers' should be 'members', req.params should be req.body, form can only have the csrf hidden field once otherwise forbidden
removed node_modules from repo
