Merge branch 'master' of github.com:biojava/biojava
* 'master' of github.com:biojava/biojava: (36 commits) Add some tests for negative residue ranges Minor javadoc & warnings fixes Fix compilation errors from merge Fix MultipleAlignmentJmol resizing bug Fixed bug where bonds from struct conn records were not made for multiple models. Latest ECOD now contains string quotes around some data fields. Need to remove them for junit tests to parse. update test for type of group based on comments from @josemduarte Fixing cath urls according to their final layout [maven-release-plugin]prepare for next development iteration [maven-release-plugin]prepare release biojava-4.2.4 new utility class for chromosome mappings. adding new dependency on guava new utility class for chromosome mappings. new utility class for chromosome mappings. Adding test for genome mapping Complete new CATH file names biojava#546 and biojava#544 Fixing biojava#544 and improving logging Some work towards fixing biojava#544 Back-porting cloning fix (see biojava#541) into bugfixes-4.2 biojava#542 changing default SCOP download location to Berkeley- SCOP. ...
