Overview
Service that manages a graph database, intended to be deployed any number of times, each instance managing one graph within a project. Most relationships will be stored here, other services can duplicate relationship data if they choose or can use this graph as their source.
As the project grows relationship data can be extended to allow for analysis of relationships, weighting same type connections etc..

Planning all Put/Update/Delete queries to pass through an API/Lambda, however Read/Get queries are able to query the graph directly.
