[ihumphrey]

Prerequisites:

• bundle xyz merged into cmake -- Merge bundle xyz into dev #455
• isis3_mosaic_tracking merged into cmake -- Merge isis3_mosaic_tracking into cmake #458
• development applications integrated into cmake -- Integrate development applications into cmake branch #461
• outstanding PRs needed in release merged into dev
  • PostgreSQL -- ISIS3/cmake PostgreSQL Missing #440
  • Clementine -- Added Clementine UVVIS distortion model. #450
  • isis3 version update -- isis3.6.0 version update #438
  • continue through rest of outstanding PRs...

Requirements:

• merge dev into cmake
• builds and tests successfully on:
  • Fedora28
  • Ubuntu18.04
  • macOS10.13
• PR cmake into dev
  • describe the changes listed above in the PR
  • reference appropriate GitHub issues
  • reference Redmine issues (5520 -- integrate cmake ; 5521 -- integrate development applications)
  • reference Redmine issues for process mosaic tracking -- add ticket number here
  • reference Redmine issues for bundle xyz -- add ticket number here

There is a lot of housekeeping to do because of simultaneously creating new infrastructure issues with GitHub issues and addressing existing Redmine issues.

Other than the tests that are failing on nightly and UserInterface (this unit test is randomly passing and failing and I am not sure why), the merge is good on MacOS 10.13.
