Added the possibility of utilizing different targets than H2 and the possibility of having this nuclei in the final state. One will need to introduce them in output/eg_pdg_table.txt. As now just charge and mass are been used. In output/eg_pdg_table.txt have been added info for deuteron and Helium3. A particle ID have to be chosen (just one need to be consisten within the code and request in the input file and check that has not yet been used for other particles (I do not follow PDG guidelines for define the PDGid))
