---------------------------------------

             Summary: Add a function to convert into a graph with canonical edges in GraphOps
                 Key: SPARK-4917
                 URL: https://issues.apache.org/jira/browse/SPARK-4917
             Project: Spark
          Issue Type: Improvement
          Components: GraphX
            Reporter: Takeshi Yamamuro
            Priority: Minor


Convert bi-directional edges into uni-directional ones instead of 'canonicalOrientation' in
GraphLoader.edgeListFile.
This function is useful when a graph is loaded as it is and then is transformed into one with
canonical edges.
It rewrites the vertex ids of edges so that srcIds are bigger than dstIds, and merges the
duplicated edges.
