Ceres 2.2.0 Backward Incompatible: LocalParameterization has been removed, use Manifold instead

[luccosta]

Hello there,

I've tried to use the last version of Ceres (4 weeks old), but when compiling it was missing ceres/local_parameterization.h so I've seen in changelog the warn "LocalParameterization has been removed, use Manifold instead".

To continue using fuse I've downgraded Ceres to 2.1.0 and it worked, so it would be nice to have some advise in doc until the transition to Manifold.

Cheers!
