- At version 2.1, gflags changed from using the google namespace, to
using gflags by default. However, it can be configured at build time
to be something else (which would be google for legacy compatibility
unless you were evil).
- Ceres previously assumed that gflags was in the google namespace.
- Now, FindGFlags.cmake extracts the namespace when gflags.h is found
and saves it in GFLAGS_NAMESPACE.
- When building the tests and examples that require gflags,
CERES_GFLAGS_NAMESPACE is defined to be the detected namespace, and
all tests/examples now use CERES_GFLAGS_NAMESPACE:: instead of
google:: when calling gflags functions.

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.
