The program is run as follows:
python aida_root_converter.py <file name of AIDA tree> <name of AIDA Tuple to be converted>
It produces a ROOT file where the .aida ending of the AIDA tree is replaced by .root. The name of the TTree is the same as the name of the AIDA ITuple that is passed as the second command-line argument. The names and types of the branches correspond to those in the AIDA file.
