API Methods for creating + adding new relationships between nodes

Start of AtomicOperation Node's Type Info

Start of API for managing relationship between nodes

ID/Group Node Freeing

Graph init/free

Finish defining "data" node

Code reshuffling - Separate out code shared between ID/Group nodes

Tidying up fixes

* Data node "add_to_graph()" needs to use DEG_get_node() not DEG_find_node()
as parent may not exist yet (it can occur in bizzare cases)

init_data() for ID Node

remove_from_group() for Groups

Distinguish between "adding node to graph" and "adding new node to graph"

remove_from_group() for Data nodes

transfer_nodegraph_to_group() -> deg_group_add_nodedata()

Renamed helper function for transferring ID/Group node data over to
group to have a more consistent API

Assorted fixes * Properly clean up after freeing node data * Removed obsolete comment

Simplify group nodes transfer code

Now that we've added a bunch of wrappers around low-level operations
invovled in doing this, we can use these to abstract and simplify the
code. The old code simply served to show us where the problems were...

Node freeing method

API call used for just adding an existing node to graph

Finish up some more group merging code

* Freeing nodes
* Relationship linking

API method for removing nodes from graph

TODO: still need to figure out what to do with relationships when doing this

Skeleton logic for creating groups
