 /**
  * Fetches rows by primary key.  The argument specifies one or more primary
  * key value(s).  To find multiple rows by primary key, the argument must
  * be an array.
  *
  * This method accepts a variable number of arguments.  If the table has a
  * multi-column primary key, the number of arguments must be the same as
  * the number of columns in the primary key.  To find multiple rows in a
  * table with a multi-column primary key, each argument must be an array
  * with the same number of elements.
  *
  * The find() method always returns a Rowset object, even if only one row
  * was found.
  *
  * @param  mixed $key The value(s) of the primary keys.
  * @return \Micro\Database\Table\Rowset\RowsetAbstract Row(s) matching the criteria.
  * @throws \Micro\Database\Table\Exception
