FEBio exporter integration
Currently, the FEBio export is not registered with the SMTK exporter operation-group. It should be, so that users can choose FEBio as a format for saving data in aeva's "Save As" dialog.
In order to be a member of the
smtk::operation::ExporterGroup, the operation must be modified to accept association to resources, not just models as it currently does.
