Improve the manual ingest via GUI or use of a tree data model

[vikhari]

One of the primary paradoxes with manually creating data (this POC) and/or using the Python API (rename pending) via a REST service (this POC is unreleased at this time) was that an end user needed to understand the hierarchical/encapsulation structure of the ontology in order to properly create the CASE data. This problem still existed during the development of this DC3DD/CLI POC. To improve this, a front-end GUI or back-end data model that allowed the user to get feedback would be useful.

Something like this would allow for a user to get instant feedback and not have to worry with weird custom encapsulation syntax (at the time used to get the POC to completion fast):

Note that this same issue fundamentally exists in the Python API example, except that it gives the user feedback at runtime that a parent concept is missing.
