+ * :: Experimental ::
+ *
+ * Helper trait for making simple [[Params]] types readable. If a
[[Params]] class stores
+ * all data as [[org.apache.spark.ml.param.Param]] values, then extending
this trait will provide
+ * a default implementation of reading saved instances of the class.
+ * This only handles simple [[org.apache.spark.ml.param.Param]] types;
e.g., it will not handle
+ * [[org.apache.spark.sql.Dataset]] or
[[org.apache.spark.ml.linalg.Vector]].
