+A `ghostfunction` leverages OpenAI GPT-4 to return sensible outputs from functions without
+defined logic. It packages the the function name, docstring, and signature into a prompt
+which is sent to OpenAI's GPT-4 API, and transparently handles coercing the api result
+into the expected return type.
