/** \name Node Tree Iterator
*
* Utility macro for visiting every node tree in the library data, including local bNodeTree blocks in other IDs.
* This avoids the need for callback functions and allows executing code in a single inner code block.
*
* Variables:
*
* nodetree: The actual bNodeTree data block.
* Check nodetree->idname or nodetree->typeinfo to use only specific types.
*
* id: The owner of the bNodeTree data block.
* Same as nodetree if it's a linkable node tree from the library.
*
* Examples:
*
* \code{.c}
* FOREACH_NODETREE(bmain, nodetree, id) {
* if (id == nodetree)
* printf("This is a linkable node tree");
* } FOREACH_NODETREE_END
*
* FOREACH_NODETREE(bmain, nodetree, id) {
* if (nodetree->idname == "ShaderNodeTree")
* printf("This is a shader node tree);
* if (GS(id) == ID_MA)
* printf(" and it's owned by a material");
* } FOREACH_NODETREE_END
