DirMulti: Shuffle code
CitationInfluence: Use sampleProb instead of prob
SharedTaste: Use sampleProb instead of prob
Core: Rip out prob
DirMulti: Introduce obsProb
DirMulti: Implement likelihood with obsProb
DirMulti: INLINE obsProb
Dirichlet: Add INLINEs
CitationInfluence: Cache dCitingNodes
CitationInfluence: Avoid creating and throwing away maps during init
CI: More initialization optimization
CI: Kill dCitedNodeItems

This was terribly inefficient
CI: Kill reference to dCitingNodeItems
CI: Fix oops
CI: arcTopicMixture: Rewrite using obsProb
CI: topicCompatibility: Rewrite using obsProb
SharedTaste: topicCompatibility: Rewrite using obsProb
DumpCI: Sort edge mixtures
RunCI: Fix edge count output
DirMulti: INLINE obsProb
