YAML files structure (Buddy)

The .yaml format structure is as follows:

• Root [dict]
  • Errors [list of dict]: Specific error codes
    • printers (optional) [list of string]: same as root-level printer filter
    • code [string]: Error code in the format XXYZZ
      • Leave XX as XX, the code applies to multiple printers.
      • For example XX101
    • title [string]: Error message title
    • text [string]: Error message string
    • id [string]: Error identifier used for referencing the error in the code
      • For example BED_MINTEMP_ERROR
    • approved [bool]: Not really good for anything
