Add example application which is based on bundle adjustment code from Libmv library, which is heavily used in Blender. Apart from bundle adjustment code this commit also contains real-life optimization problems from VFX pipeline. This files are created from production files of Tears of Steel movie. New code is placed to examples, and could be used either as an example implementation of BA or for timing investigation of problems appearing in VFX. Problems for this application are placed to data/libmv-ba-problems. Usage: ./libmv_bundle_adjuster --input=/path/to/problem_file.bin There's also optional flag --refine_intrinsics which declares explicitly whether intrinscis shall be refined or not. If this flag is not passed, refinement will happen for problems stored in image space. Structure of problem files is described in header comment of libmv_bundle_adjuster.cc.
