Create light admin interface

[dahnag]

Specific need: mechanism for contacting all users. The easiest implementation would likely be the ability to extract email addresses.

The ideal is to set this up in a way that will be extensible.

Email address access is a V2 issue; anything else will be V3.

Note, this is a good initial mongo query:

db.users.aggregate([
   {
     $lookup:
       {
         from: "profiles",
         localField: "_id",
         foreignField: "userid",
         as: "user_profiles"
       }
  },
  {
     $lookup:
       {
         from: "grants",
         localField: "_id",
         foreignField: "userid",
         as: "seeker"
       }
  },
   {
     $lookup:
       {
         from: "makers",
         localField: "_id",
         foreignField: "userid",
         as: "maker"
       }
  }
])
