Hi Luis,

take a look at https://github.com/bloyl/itkSpatialObjectWriters, I've added
you as a collaborator.

It still needs to support other SpatialObject classes. I plan on adding
itkBoxSpatialObject support as I have a need for it. I also want to add
support for both the spatialObjects world Transforms as well as an
additional transform, as well as adding attaching some metadata such as
name or id.

Let me know what you think.
Best,
Luke
