How to create new examples under the MRPT tree:
--------------------------------------------------------

1) Go to [MRPT]/samples

2) Create a directory with the example name, e.g. "foo" ->
   [MRPT]/samples/foo/

3) Create the C++ file and save it as "test.cpp":
   [MRPT]/samples/foo/test.cpp

4) Add the example name to any of the lists in:
   [MRPT]/samples/CMakeLists.txt

5) In the build directory, run "cmake . -DBUILD_EXAMPLES=ON"

6) An automatically generated CMake script will be created in:
   [MRPT]/samples/foo/CMakeLists.txt

7) Commit BOTH the source file and the CMakeLists.txt files:
   git add [MRPT]/samples/foo/test.cpp [MRPT]/samples/foo/CMakeLists.txt

8) Optional: Add a [MRPT]/samples/foo/README.md and a screenshot in
   [MRPT]/doc/source/images/foo_screenshot.{png,gif},
   then rerun [MRPT]/scripts/generate_rst_docs_examples.sh
   and add it to the list in [MRPT]/doc/source/examples.rst

done!
