Upload artifacts to Central Repository - ced2arddigenerator

[CSimmer]

Put the CED2AR v2 project releases into a Central Repository so they can be available for immediate use.

Projects and artifacts must meed certain requirements before they can be uploaded to the Central Repository. The requirements are at: Guide to uploading artifacts to the Central Repository

At first glance, the 5 CED2AR v2 project repositories:

1. Do not have the required 16 metadata elements. (Most have 4 of the 16.)
2. One project needs to be refactored and tested to meet the requirements. (These are breaking changes.)
3. Some unused code may need to be deleted.
4. Project dependencies and versions may need to be updated and tested before being uploaded.
5. Projects do not have the attached javadoc and source code included in the releases. (Need to add plug-ins.)
6. Projects need to have valid PGP signatures.

There will be one github issue per project.

High level tracking of these 5 git repos are in: v2 maven publishing requirements.
