transition ogre code to archimedes version of tinkergraph

After the merge there were two ns's which had tinkergraph implementations, ogre.tinkergraph (from ogre) and ogre.graph (from archimedes).

This PR deletes the ogre.tinkergraph ns and replaces all references with ogre.graph (along with ogre.element, vertex, and edge)

There were some minor api conflicts, primarily getting an element from a property

```
archimedes:
(get element :key)

ogre:
(get :key element)
```

I went with the archimedes version, which resulted in a lot of test code changes from
```
(partial get :key)

to

#(get % :key)
```
