add new test for version v0.6

Changes for v0.6:

* remove PedestrianOverlapDistProcessor and add functionality in
* show overlap distance in PedestrianOverlapProcessor as a positive
* 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.
