Haskell Research 1: Data type as input, data type plus instance declaration as output

[HinsonSIDAN]

We want to explore this functionality due to issue 4. Taking example-validator as example:

-- Param data type
data TestParam = TestParam {

Given that frontend could handle this logic seamlessly upon research, closing this issue until community requests for the function
