    Jaronuinga is a simple JSON Schema validator written in Java 17. It is based on JSONP 1.1 and has no other dependencies.
    The library's primary purpose is to intercept the parsing process for additional custom analysis (e.g., verifying "foreign keys" on data submission).
    It may also be used for schema analysis via `getParent()` and `getChildren()` methods.
