Implemented black-box test cases

* the directories below "./test" contain test cases
** "transformation.xsl" and the expected result as "reference.xml"
** tests are performed by "check.sh"
*** returns diff on error
* this system enables simple verification of external function results
** way simpler than C++ unit tests would be in this scenario
* expanded cmake instructions to automatically execute the test cases
* old example transformation was removed
