Updating Google Calendar and Contacts from Google Ford

I'm not a programmer of modern languages, I graduated from college with a > programming degree in 1987 but got employment in computing hardware not > software.

I slightly modified the following code to update my calendar from a google > form. The code works great but now I'd like to add the email address and > name to Google contacts if it doesn't exist, can anyone help please?

//Load the Moment.js library once.
var moment = Moment.load();

var GLOBAL = {
  //the id of the form we will use to create calendar events 
  formId : "19qtJNTy-ja7QBc54lZqTDQDX-sD4vg-not compleate",  

  //the id of the calendar we will create events on
  calendarId : "[email protected]",


 //a mapping of form item titles to sections of the calendar event
  formMap : {
    eventTitle: "Name",
    startTime : "Date and Start Time",
    endTime: "End Date and Time",
    description: "Brief Description of Event",
    location: "Location",
    email: "Email",
    contact: "Contact Number"

  },
}

function onFormSubmit() {
  var eventObject = getFormResponse();
  var event = createCalendarEvent(eventObject);
}

function getFormResponse() {
  // Get a form object by opening the form using the
  // form id stored in the GLOBAL variable object
  var form = FormApp.openById(GLOBAL.formId),
      //Get all responses from the form. 
      //This method returns an array of form responses
      responses = form.getResponses(),
      //find the length of the responses array
      length = responses.length,
      //find the index of the most recent form response
      //since arrays are zero indexed, the last response 
      //is the total number of responses minus one
      lastResponse = responses[length-1],
      //get an array of responses to every question item 
      //within the form for which the respondent provided an answer
      itemResponses = lastResponse.getItemResponses(),
      //create an empty object to store data from the last 
      //form response
      //that will be used to create a calendar event
      eventObject = {};
  //Loop through each item response in the item response array
  for (var i = 0, x = itemResponses.length; i<x; i++) {

        //iterated on
