add test and checkstyle support

All tests are in "tests" directory.
To run tests use:
  make test
For verbose output use:
  export V=2;make test ARGS="-V"
Test log file is generated in:
  Testing/Temporary/LastTest.log

To run checkstyle for the current commit use:
  ./scripts/checkstyle.sh
To run full check on all files use:
  ./scripts/checkstyle.sh --full
