This patch adds an integer identifier to nodes that doesn't change when the node name changes. This identifier can be used by different systems to reference a node. This may be important to store caches and simulation states per node, because otherwise those would always be invalidated when a node name changes. Additionally, this kind of identifier could make some things more efficient, because with it an integer is enough to identify a node and one does not have to store the node name. I observed a 10% improvement in evaluation time in a file with an extreme number of simple math nodes, due to reduced logging overhead-- from 0.226s to 0.205s.
