[misc] Updated code to work with the latest phenotips snapshot
Edited MutualInformationPatientSimilarity scoring to look only at set of ancestors, and not weighted counts of each node
Merged in changes from upstream remote
[misc] Added missing dependency
Merge branch 'master' of https://github.com/phenotips/patient-network
Updated mutual information patient similarity to use harmonic mean of scores, to just use direct ancestor overlap (rather than weighted by count), and tightened conditional IC bound (untested).
