title: cypher path with condition on relationship direction
body: <p>I want to find all paths given a start node </p>
  
  <pre><code>MATCH path=(n)-[rels*1..10]-(m) 
  </code></pre>
  
  <p>with the following 2 conditions on path inlcusion: </p>
  
  <ol>
  <li>true if relationship between subsequent nodes in path has property PROP='true' </li>
  <li>if <code>type(relationship)=SENDS</code> then true if direction of the relationship is outgoing (from one path node to the next node in the path)</li>
  </ol>
  
  <p>Another way of phrasing this is that direction doesn't matter unless the relationship name is SENDS </p>
  
  <p>I can do condition 1 with <code>WHERE ALL (r IN rels WHERE r.PROP='true')</code> however ive no idea how to do condition 2.   </p>
