Code refactoring
* Moved the classes into com.riskified.*
* Converted all public attributes to private and provided getters and setters.
* Moved the properties file into src/main/resources and read it from there. Used the same during mvn initialization.
* Ignored idea and eclipse related files.
* Deleted the lib folder as the dependencies were in the pom.
