Can we add some examples of test programs to use libwave for stuff to the readme or documentation?

As we had with MCPTAM, and now that we can build maps from lidar data, can we set up a default test bag on the wavelab server, and provide instructions to build a static map with it? Same for a VO set, and a gimbal calibration. All when these demos are working, of course.

Some considerations for adding examples

• Large data files can be downloaded automatically with CMake's ExternalData when an example is built: Handling binary assets and test data with CMake
• Output of examples should be tested, to make sure they stay functional
• There are ways to include examples in Doxygen so that the example code and output are separated (e.g. How to integrate examples with Doxygen?), though this isn't a huge priority
