[E4graph-core] Using unique IDs instead of Node/Vertex classes.

[Khorev S. <Khorev@SoftLab.RU>]

This list seems to be ve-e-e-ry silent :))
I'm trying to implement persistence for MzScheme using e4Graph.
Have some questions:
1) The current version is 1.09 alpha. Does "alpha" relate to code quality or
feature set? It seems that e4Graph has good code coverage by tests, am I
right?
2) I don't want to expose full e4Graph interface to Scheme (at least for
now) because Scheme has its own good data structures :) But I want to store
this "good data structs" with e4Graph. And I don't want to store e4_Nodes
and Vertices in memory, managed by MzScheme GCollector.
So, are the following actions safe?
e4_Storage stg;
e4_Node node; 
... // here goes node loading
e4_NodeUniqueID uid;
node.GetUniqueID(uid);
int saved_node_id = uid.GetUniqueID();
...// here goes other actions WITHOUT closing storage
e4_Node node2; 
e4_NodeUniqueID uid2;
uid2.SetUniqueID(saved_node_id, stg);
stg.GetNodeFromID(uid2, node2);
assert(node == node2)
