Jakob Homan updated GIRAPH-62:
------------------------------

    Attachment: GIRAPH-62.patch

Patch to create a new vertex reader, which is parameterized on the type of the 
id, its edge and edge values.  Implementers just have to fill in these methods 
to ready a new adjacency list encoded as above.  One is provided for lists 
where the id is a long and the edges and values are doubles, a common format.  
I've tested this against a modified pagerankbenchmark (patch coming) and every 
works as expected.  Introduces mockito for unit testing.
                
> Provide input format for reading graphs stored as adjacency lists

> We should provide as many options for getting data in/out of Giraph as 
> possible.  One common format is adjacency lists, with each edge id, its 
> value, and its edges and their values per line.  It would be good to provide 
> inputformats to handle this type of data with minimal effort from the user.
