			= Naming in coding conventions =

			== Node Labels and Relationship Types ==

			There is the possibility these might need to be changed in the future eg if clash with other graphs being combined or to match other graphs, or if Neo4j changes its engine, they will also be referenced extensively through code, for this reason we will use code constants to create the names or parts of names for Node Labels and Relationship Types.

			== Node and Relationship properties ==

			There is less likelihood of these needing to be changed in the future so we will hard-code strings through our code to reference them, this is easier to read than constants.
