• add API using sample data (no database)
• at http://localhost:3000/source?source_name=sample
• response: { source: { file: "sample", source: "object HelloWorld { def main(args: Array[String]) { println("Hello, world!") } }", entities: [ "Array", "String", "println" ] }, entity: [ { name: "Array", url: "http://www.scala-lang.org/api/current/#scala.Array" }, { name: "String", url: "http://www.scala-lang.org/api/current/#scala.Predef$" }, { name: "println", url: "http://www.scala-lang.org/api/current/#scala.Console$" } ] }

One more depth directory which means the name of source requested has been added. If the name doesn't exist, 404 response will be sent. http://localhost:3000/source/sample

And please split the test code and the prod code and don't name an object as only 'test'.
