docs: Create a new container.
  
  When a new container is created, no check is done against the server
  to ensure that the container exists. Thus, it is possible to have a
  local container object that does not point to a legitimate
  server-side container.
  
  @class Container
  @constructor
  
  @param {String} name The name of the container.
  @param {String} token An authentication token.
  @param {String} url The URL of the container.
