 # Usage
 Just replace `JSONDecoder` with `ReerJSONDecoder` wherever you want to use it. So instead of `let decoder = JSONDecoder()`, do `let decoder = ReerJSONDecoder()`, and everything will just work. This is because `ReerJSONDecoder` has the exact same API as `JSONDecoder`. Also, don't forget to add `import ReerJSON` in files where you use it.
