/* This script (roughly) demonstrates the following:
 * 
 * 1. Load a file consisting of comma separated values for input data and graph names (/path/to/file,graphName)
 * 2. Insert all the information into Graphulo as Adjacency graphs
 * 3. Load results from a single, hard-coded graph (SimpleAdjInsertTest)
 * 4. Dump the first ten rows from the graph
 *
