CHEFS examples lack consistency

[WalterMoar]

The example forms in CHEFS lack consistency in:

• name of the .JSON files that can be downloaded (chefs_example__something_something.json?)
• code shown in the documentation must match what is in the JSON files
• JSON files must match what is deployed in CHEFS
• CHEFS examples should only be owned by CHEFS team
• Examples should not produce console errors, even if it means the JavaScript is more complicated. When less technical users cut and paste from the examples it's more difficult to help them debug if the console is full of errors.

Definition of Done

• Update the Style Guide with a description of the naming convention (and anything else) related to examples
