+   * @param $alias
+   *   The alias to create. If not specified, the alias will be $table_$field

+   *   alias be used.
+   * @param $params
+   *   An array of parameters additional to the field that will control items
+   *   such as aggregation functions and DISTINCT.
+   *
+   * @return $name
+   *   The name that this field can be referred to as. Usually this is the alias.
