A bug in tree_connector.php

im0 in the 2,3 row should be im1 and im2.

function to_xml_start(){ ...... if ($this->im0) $str1.="im0='".$this->im0."' "; if ($this->im1) $str1.="im1='".$this->im0."' "; if ($this->im2) $str1.="im2='".$this->im0."' "; ...... }

Thaks for remark, it is already fixed in dev. build
