Compliance Checker 4.2.0
Reformatted ACDD output to include more informative, less repetitive error messages. Functional changes from pull request #624 include enhanced grouping for "grouped checks" (e.g. Global Attributes), which condenses the results into fewer lines and more appropriate sections (other checks will also be able to leverage this new formatting improvement, not just the ACDD checks).
- addresses issue #620
- leverages existing sorting/grouping functionality
- reduces repeated code
- improves inline documentation
