The purpose of this PR is to fully and automatically support the parsing and validation of a json object of variable values referenced by their names into a VariableValues object.
This project is using Aeson already so the interface will use the aeson AST for JSON.
The goal is to address #145, #132, and to replace #128
Schematically, the idea is to follow the generation of the schema by a double tree descending job where we compare the GraphQL's expected type and the JSON's observed value to either return an error or return the expected Haskell/GraphQL value.
For now, the code will reuse the Validation module and the execution module. The actual variables parsing will be done in the Validation module.
