/**
   * List
   *
   * The use of having `list` method is, you can create your own statics
   *
   * Example:
   *
   *      UserSchema.static({
   *        deleted: function (cb) {
   *          this.list({
   *            criteria: { deleted: true },
   *            sort: { name: 'desc' }
   *            limit: 20,
   *            populate: [{
   *              path: 'company', select: 'name', match: { deleted: false }
   *            }],
   *            select: 'name email'
   *          }, cb)
   *        }
