- It works with our affine camera matrices estimated from the H&Z algorithm

For path operator +=

Added 'header-only' and changed the publication to the ICIP paper.

Added cereal include directory to CMake

In preparation for the serialisation - and declared it empty, to work around a VS bug with =default
