/* This class extends phplibs template.inc Template class 
 - automatic block detection / declaration including nested blocks
 - auto blanks unused blocks 
 - allows specification of template ihtml file, template path, handle in one line instead of many

 to get phplib template class go to 
 https://sourceforge.net/projects/phplib/
 - thanks to phplib for such an excellent template class :)
