> Add methods to read and write a Graph as adjacency list

> Key: FLINK-1815
> URL: https://issues.apache.org/jira/browse/FLINK-1815
> Project: Flink
> Issue Type: New Feature
> Components: Library / Graph Processing (Gelly)
> Affects Versions: 0.9
> Reporter: Vasia Kalavri
> Assignee: Faye Beligianni
> Priority: Minor

> It would be nice to add utility methods to read a graph from an Adjacency
> list format and also write a graph in such a format.
> The simple case would be to read a graph with no vertex or edge values, where
> we would need to define (a) a line delimiter, (b) a delimiter to separate
> vertices from neighbor list and (c) and a delimiter to separate the neighbors.
> For example, "1 2,3,4\n2 1,3" would give vertex 1 with neighbors 2, 3 and 4
> and vertex 2 with neighbors 1 and 3.
> If we have vertex values and/or edge values, we also need to have a way to
> separate IDs from values. For example, we could have "1 0.1 2 0.5, 3 0.2" to
> define a vertex 1 with value 0.1, edge (1, 2) with weight 0.5 and edge (1, 3)
> with weight 0.2.
