combine a Mesh object and a Node_Data object into a field
group DVcomb_mesh_and_data {

DVcomb_mesh_and_data takes two inputs, any Mesh and Node_Data, and combines them together to form a new field.
Many base module visualization objects input only the mesh of a field object (for example, DVmirror), and do not care if Node_Data is present or not. Other base module objects input only an object's Node_Data (for example, DVclamp), and do not care if a mesh is present. Yet one may presume that the user usually wants both the Mesh and Node_Data objects of his/her original field rejoined prior to further processing. The DVcomb_mesh_and _data base module object performs this rejoining.The actual effect of DVcomb_mesh_and_data is slightly more subtle. What actually happens is that references to the input Mesh and input Node_Data are merged. A reference object named out is defined that points to this merging.
Any object referencing the out port will receive a reference to the merged in_mesh and in_node. This will in turn reference the appropriate subobject of either Mesh or New Node_Data.
The following table lists which base modules work only on the mesh or only on the Node_Data, and hence may require DVcomb_mesh_and_data:

A reference to the input Mesh.
A reference to the input Node_Data.
A reference to the object that is the merge of in_mesh and in_nd.
