 * Build middleware for parsing request bodies.

 * parse request POST bodies. Once parsed the request body parameters are 
 * available in `this.request.body`.
 *
 * If `csrf` middleware is enabled is set then this validates the csrf.
 * 
 * @param {Object} options Configuration options for `co-body`.
 * @param {String} [options.limit] The maximum allowed size of a request body.
 * 
 * @return {Function} middleware
