Because I was struggling hard with default values for cdk.interfaces fields, I did not have time to write up the Bug Squash Party report for day 3 (see also day 1 and day 2). But here it is. Day 3 Kai worked hard on getting the cdk.interfaces API cleaned up, as agreed upon earlier. Christian added a test for the RMSD calculator (see getAllAtomRMSD()), and cleaned up his code a bit.
