[Insight-developers] Copy input to Output Mesh

[Michel Audette]

Hi Michael,

let me know if that works for you. I was aware of prior discussions on how
to copy components of the mesh, and I was not aware of the history as to why
there was no single function, so I was not able to make a useful
contribution.

In general, it's not a bad thing to copy to Insight Developers the way Luis
has. Others, such as ITK contributors with particular expertise on these
meshes, like Alexandre Gouillard and his collaborators, can chime in and
make useful suggestions. I recognize that it's a public exercise in
humility, and believe me, I empathize with this aspect of the learning
curve, since I'm a fairly recent convert to ITK.

Best wishes,

Michel
