[jrgriffiniii]

This follows the proposed maintenance reorganization within samvera/maintenance#137.

In order to consider this completed, the following tasks must be completed:

• Migrate to samvera-deprecated samvera-deprecated/browse-everything-redux-react#93
• Updating the README to clarify that this project has been deprecated samvera-deprecated/browse-everything-redux-react#94
• Migrate to samvera-deprecated samvera-deprecated/browse-everything-components#16
• Updating the README to clarify that this project has been deprecated samvera-deprecated/browse-everything-components#17
• Migrate to samvera-labs samvera-labs/parcel-browse-everything#7
• Updating the README, SUPPORT, and package metadata in order to migrate the repository into the samvera-labs samvera-labs/parcel-browse-everything#8
• Demonstrate https://github.com/samvera-labs/parcel-browse-everything

samvera-labs/parcel-browse-everything#6 ensures that this is prepared for minimal usage and testing.
