CLOSE - WD02 - Define grammar for and examples of using Relationship templates

Currently, we have a "requirements" clause for a Node Type or Node Template where our only usage example is to have a custom Relationship Type (ie. WordPressDbConnection) used; however, it a preferred usage is not to encourage creation of new types (especially connection relationship types), but instead to use templates to augment existing types to preserve simplicity.

This means we should define Relationship Templates and encourage their use where possible (by example).
