{- 

MAMonad:
- A monadic structure, MAMonad, designed to abstract over various content types (e.g., Video, Audio, Text) and facilitate transformations between them using a Large Language Model (LLM).
- Type: MAMonad :: * -> *

Bifunctor-like Error Handling:
- MAMonadResult is a bifunctor-like structure encapsulating either a result (Success) or an error (Error).
- Type: MAMonadResult a b = Success a | Error b

MAMonadContent Type Class:
- A class representing content that can be processed by MAMonad. It includes a function to extract keys using an LLM.
- extractKeys :: LLM -> a -> IO (MAMonadResult [Key] ErrorType)

Functor, Applicative, and Monad Instances for MAMonad:
- Functor: fmap applies a function inside the MAMonad.
- Applicative: pure wraps a value in MAMonad; <*> applies a monadic function to a monadic value.
- Monad: >>= (bind) chains operations on MAMonads, handling both success and error paths.

Transformation Function:
- transformContent utilizes the LLM and extracted keys to transform one content type to another within the MAMonad structure.
- transformContent :: (MAMonadContent a, MAMonadContent b) => LLM -> a -> MAMonad b

Content Types (e.g., Video, Audio):
- Specific data types representing different content modalities, each implementing MAMonadContent to enable key extraction and transformation.
