Fixed an issue related to feature where physics list is added at the macro. It must be declared before the /run/initialize command in the macro. See macros/runexample.mac

Now physics list is no longer hard coded in the remoll.cc Physics lists available: FTFP_BERT FTFP_BERT_EMV FTFP_BERT_EMX FTF_BIC LHEP LHEP_EMV QBBC QGS_BIC QGSP QGSC_BERT QGSP_BERT QGSP_BERT_EMV QGSP_BIC_EMY QGSP_BERT_EMX QGSP_BERT_HP QGSP_BIC QGSP_BIC_HP

Now EM and hadronic processes can be turned ON/OFF independently at the macro. See macros/runexample.mac

Now optical physics processes can be turned ON/OFF. Currently it is turned OFF by default. See macros/runexample.mac
