Customizing to project, updating project description, removing reference to Spark Example Project (SparkExampleProjectBuild.scala renamed to ProjectBuild.scala), remove reference to Spec2 and replace with JUnit4 since I prefer it, update WordCountJob to use App signature instead of main(), update WordCountTest to use JUnit4 instead of Specs2.
Initial commit for local mode (code and tests).
Removing WordCount scaffolding since no longer required.
Making all tests run in sequence by creating and destroying the SparkContext within each test.
Refactor out test name.
Adding Python script to draw disease interaction graph.
Fixing input path to larger (still test) dataset and filtering on similarity so we get a less cluttered graph.
