DataService will now do most of the program's operations correctly and
in order. Run with args: "gousiosg java-callgraph" (no quotes) to test.
Also need the java-callgraph git repo in default path.
Didn't finish teh last commit message:

Running the program will crawl the repo, and pass the JAR to
java-callgraph and store the result in result#.txt. Need to just figure
out how to pass the author info and results to the parser and inject the
json files...
Added TEMP folder that contains the jars to ignore.
