[antlr-interest] gunit tree testsuite can't find the group template file

Hi Stanislas,

gUnit currently can only test on plain parser/tree grammar, and  
doesn't support loading group file(*.stg) or setting customized tree  
adaptor yet.
The functionality such as walker.etTemplateLib() and  
parser.setTreeAdaptor() will be added into the next release. Sorry  
for the inconvenience.
