Righto version of https://derickbailey.com/2016/09/27/ending-the-nested-tree-of-doom-with-chained-promises/

chained.js

// Assumes <Thing>.get is a normal err-back API.

var json = righto.from(xmltojsonhttpclient.get()),
    transform = righto(SearchModel.get, json),
    mappedData = righto(SearchController.get, transform),
    contractData = righto(ContractModel.get, mappedData),
    mappedContractData = righto(ContractController.get, contractData);

mappedContractData(function(error, result){
    // Do what you want.
});

I'm assuming the .get() calls in the original return promises, and I'm thinking there may be a case that can be added to righto that handles tasks that return promises or rightos, but that will be based on future requirements.

EDIT: Meh, I added it: https://gist.github.com/KoryNunn/999c5578ef2144986d3bcb4f2ae246d0
