title: Neo4j - Relationship Expander deprecated, using Lowest Common Ancestor
body: <p>I'm looking to use the lowest common ancestor method here: 
  <a href="http://grepcode.com/file/repo1.maven.org/maven2/org.neo4j/neo4j-graph-algo/1.8.M03/org/neo4j/graphalgo/impl/ancestor/AncestorsUtil.java?av=f" rel="nofollow">http://grepcode.com/file/repo1.maven.org/maven2/org.neo4j/neo4j-graph-algo/1.8.M03/org/neo4j/graphalgo/impl/ancestor/AncestorsUtil.java?av=f</a></p>
  
  <p>I got it working with the RelationshipExpander but that class is deprecated in favor of PathExpander, however I don't see how to apply PathExpander in this case. </p>
  
  <p>Example here: 
  <a href="http://grepcode.com/file/repo1.maven.org/maven2/org.neo4j/neo4j-graph-algo/1.8.M03/org/neo4j/graphalgo/impl/ancestor/AncestorTestCase.java?av=f" rel="nofollow">http://grepcode.com/file/repo1.maven.org/maven2/org.neo4j/neo4j-graph-algo/1.8.M03/org/neo4j/graphalgo/impl/ancestor/AncestorTestCase.java?av=f</a></p>
  
  <p>Any pointers? </p>
