minor post-processing initial Integration

Well, markers need to be "post-processed", so the atoms must already be in the atomspace.

I think to make all these "post-processing" works with SuReal, we need to change the output of R2L helper functions to include something like:

```
ReferenceLink
   ParseNode "sentence@1332543252"
   InheritanceLink
      ConceptNode "Socrates@32432"
      ConceptNode "men@54654"
```
So basically wrap each **individual** link created by R2L in a ReferenceLink or something.
