Patch Parser

Aeson

Patch {op :: Text, path :: Text, from :: Maybe Text, value: Maybe Text} deriving (Data, Typeable)

Data Parser

Aeson
Traverse the AST or use a heterogenous list type?
Heterogenous list should probably get turned into a tree
- Manually traverse the tree or turn it into a Map instead?

Data Transformer

MapPatch
- Already Implemented
TreePatch
- Need to implement

Writing Changes

I think Aeson has a thing for converting from data to JSON text
