Improving TestAltLocs and fixing issue with SiftsChainToUniprotMapping
- now TestAltLocs will test 3PIU with both pdb and cif parsers, before
it depended whether the AtomCache was initialised to one or the other
type of file so result was a bit unpredictable
- SiftsChainToUniprotMapping was not downloading the sifts file and
simply reading a blank file. This was making the corresponding test fail
if run stand-alone (not if run as part of a full mvn intall, in that
case the file was getting downloaded by a previous test)
