Problems with syncretic promotion - we handled post-advice, but not pre-advice.
Consider the following:

    elements: {
        output: {
            type: "fluid.csvFileOutput",
            input: "{joined}.data",
            filePath: "outputData/output.csv",
            writeProvenance: true
            // provenance: "provenance.csv",
            // provenanceMap: "provenanceMap.json"
        }
    }


This is actually:

elements: {
    joined: {
    …. stuff
    },
    output: {
        type: “fluid.fileOutput”,
        input: "{joined}.data",
        parents: “fluid.withEncoding.csv”,
        filePath: “outputData/output.csv”
    }

but then we want the encoder to expand to


    output: {
        elements: {
             input: { <--- This bit is done by the promoter - how does it know?
                 value: “{joined}.data”,
             },
             encoding: { <--- This bit appears in the grade
                 type: “fluid.encoding.csv”,
                 input: “{input}.data”,
             },
             main: {
                 type: “fluid.fileOutput”,
                 input: "{joined}.data", < --- Must be rewritten???! How do we know? And what to?

                 filePath: “outputData/output.csv”
        }
