streaming api full json comaptible

[kilianc]

We should ad a parameter to responseStreamStart specifying the kind of input or the start/end stream strings.

The main goal is to make something like this possible:

MyApiModule.prototype.testPublic = function(request, response) {

    var self = this;

    // start/stop strings
    self.emit("responseStreamStart", request, response, 200, null, ['{', '}']);
    // or json type defined in apimodule.js
    self.emit("responseStreamStart", request, response, 200, null, ApiModule.responseStreamTypes.OBJECT);

    var myAsyncEventEmitter = new SomethingAsync();

    myAsyncEventEmitter.on('data', function(err, item){
        self.emit("responseStreamData", request, response, { key: randomKey(), value: item }, false);
    }

    myAsyncEventEmitter.on('end', function(err, item){
        // last object (avoiding trailing commas)
        self.emit("responseStreamData", request, response, { key: randomKey(), item: item }, true);
        self.emit("responseStreamEnd", request, response);
    }
}

this should produce a response like this

{
    "random1": { /* item content */ },
    "random2": { /* item content */ },
    "random3": { /* item content */ },
    "randomN": { /* item content */ },
    ...
}
