    +/**
    + * This example shows how to use Gelly's library methods.
    + * You can find all available library methods in [[org.apache.flink.graph.library]].

    + * 
    + * In particular, this example uses the
    + * [[org.apache.flink.graph.library.ConnectedComponentsAlgorithm.GSAConnectedComponents]]
    + * library method to compute the connected components of the input graph.
    + *
    + * The input file is a plain text file and must be formatted as follows:
    + * Edges are represented by tuples of srcVertexId, trgVertexId which are
    + * separated by tabs. Edges themselves are separated by newlines.
    + * For example: <code>1\t2\n1\t3\n</code> defines two edges,
    + * 1-2 with and 1-3.
