Simple service API's for accessing the GeoLink triple store

This is mostly a set of sandbox services to allow for further discussions with groups interested in exploring the use of GeoLink in thier efforts.

Examples will be coming. However, we plan to implement swagger-ui relatively quickly in order to provide an initial interfaces.

• Enable SWAGGER UI: ref: https://github.com/emicklei/go-restful/tree/master/swagger
• Also should make a DOAP file for this effot.

Need to look this over and see if this will be useful to this approach: https://github.com/UKGovLD/linked-data-api/blob/wiki/API_Deployment_Example.md

Do we want the RESTful API to follow OpenSearch patterns? (likely yes, at least at the start)
