METHOD_MAP =

How we map http methods and the indirection name in the URI to an indirection method.

{
  "GET" => {
    :plural => :search,
    :singular => :find
  },
  "POST" => {
    :singular => :find,
  },
  "PUT" => {
    :singular => :save
  },
  "DELETE" => {
    :singular => :destroy
  },
  "HEAD" => {
    :singular => :head
  }
