Import Class Reference
Detailed Description
The Refresh mechanism supports three-stage asynchronous update consisting of load, compile, and merge.
When the UpdateVisitor encounters a newly loaded subgraph, it requests the compilation of that subgraph. The compilation is invoked by an OSG plugin which is executed on the DatabasePager thread. When the UpdateVisitor encounters a newly compiled subgraph, it merges that subgraph into the scene. So, Import is just a little state machine.

Look at the children and parents, and let us know if this node should be marked as "maintain" or not.
Return true if we really, really need that flag set. The "set...Check" behaves as the "set..." above if maintain is false. If maintain is true, it consults the "needTo..." to decide if it should set it or not. In the process, it may fix up the parents as well.
Reimplemented from Node.
