[K20shores]

Many of our tutorials use line numbers to point to the file. The auto-formatting PRs may change these.

• Check the line numbers in all tutorials #373
  • at the same time, replace all of the print state and header functions with the calls to print state on the state class itself introduced in Create simple command-line driver for MICM #308
  • you can do this by running make docs for the very first time. Any line numbers that are out of range will be reported
  • but you'll still have to read through each tutorial and make sure that the description near the code listings matches.
  • most are likely correct, but it never hurts to check again
• Tutorial for each example in the examples folder #374
