Detailed Description

The TreeStream class allows creating a root tree of any objects having root dictionary, using operator<< interface, and w/o prior tree declaration. The format is: treeStream << "branchName0="<<objPtr <<"branchName1="<<objRed <<"branchName2=" <<elementaryTypeVar<<"\n"

See testTreeStream.cxx for functional example
