add new test for version v0.6
Changes for v0.6: Processors: * remove PedestrianOverlapDistProcessor and add functionality in PedestrianOverlapProcessor. * show overlap distance in PedestrianOverlapProcessor as a positive delta * refactor NumberOverlapsProcessor to use PedestrianOverlapProcessor as dependency * refactor MaxOverlapProcessor to use PedestrianOverlapProcessor as dependency JsonTransform Tests: To test transformation and manipulate Jackson's JsonNode representation four new Interface are included. * JsonNodeExplorer: Methods to travers, delete and add JsonNodes in an existing Json representation. Many methods will throw Exceptions if a path does not exist or the operation does not work. Included are helpers for eays path traversal (i.e. path(root, "path/to/node")) * TestJsonNodeExplorer: This extends the JsonNodeExplorer and overwrites all Methods with exceptions and insted inclueds Assertions and Junit test to indicate an error. Thus for example the method pathMustExist contains an assertion test that the path exists. This can be used in UnitTest as assertions. * TestJsonNodeHelper: Create JsonNode tree from text files * TestResourceHandler: Allows to load file based resources for test and will create backups of test files so the test enviroment can be resotred if a test fails. This helps in the development process.
