/**
  * Populates the object using an array.
  *
  * This is particularly useful when populating an object from one of the
  * request arrays (e.g. $_POST).  This method goes through the column
  * names, checking to see whether a matching key exists in populated
  * array. If so the setByName() method is called for that column.
  *
  * You can specify the key type of the array by additionally passing one
  * of the class type constants BasePeer::TYPE_PHPNAME, BasePeer::TYPE_STUDLYPHPNAME,
  * BasePeer::TYPE_COLNAME, BasePeer::TYPE_FIELDNAME, BasePeer::TYPE_NUM.
  * The default key type is the column's phpname (e.g. 'AuthorId')
  *
  * @param      array  $arr     An array to populate the object from.
  * @param      string $keyType The type of keys the array uses.
  * @return     void
