Example for checking BE between some local code and the trunk for SBA modes and binaural output formats

```

./testBitexact.py -p user_linux -C SBA --oc BINAURAL BINAURAL_ROOM -srcdirtest /some/local/src/dir/ -srcdirref /home/user/ivas/automated_tests/ --svnref https://INSERT_SVN_REPO/trunk/ --svnuser user --srin 48 --srout 48

./testBitexact.py -p user_linux -C SBA --oc BINAURAL BINAURAL_ROOM_IR -srcdirtest /some/local/src/dir/ -srcdirref /home/user/ivas/automated_tests/ --svnref https://INSERT_SVN_REPO/trunk/ --svnuser user --srin 48 --srout 48
