Jargon service translates search strings for the market using community-sourced abbreviations. It also creates the jargon.yaml file in the user's save directory, for future customization (either manual, or via the UI) and provides the code hooks to load and update it. The JargonLoader is capable of hot-loading new jargon.yaml configurations without restarting Pyfa.
