Generate constructors for data only interfaces

[stheophil]

Currently, in order to generate an object of type

interface getSummaryDataOptions {
        /** Do not use aliases specified in the data source in Tableau. Default is false. */
        ignoreAliases?: boolean;
        /** Only return data for the currently selected marks. Default is false. */
        ignoreSelection?: boolean;
        /** The number of rows of data that you want to return. Enter 0 to return all rows. */
        maxRows: number;
    }

I implement a function in Javascript like

function MakeSummaryDataOptions(a, b, c) {
  return {
    ignoreAliases: a,
    ignoreSelection: b,
    maxRows: c
  };
}

plus an interface definition in typescript. It would be nice if tcjs supplied constructor functions for such objects.
