_design documents crud

[gp187]

Follow the naming convention in couch2.db and create a CRUD for design documents. Read carefully the docs, it's a bit tricky

naming convention must match the current naming convention

• docCreate >> docViewCreate
• docCreateWithId >> docViewCreateWithId
• docViewUpdate >> docViewUpdate
  ..... etc
  These refer to the actual _design document.

To call the view data, use a new convention

• callView
• callViewOrThrow
  ....

Create some sample view design documents documents

with counter and examples from here
