retrieving url from photo, need to process on client end
We refactored XMLHttp request to server. Broke out components into
FormDataPreparer and TokenScraper. TokenScarper find CSRF token, to
append in header for XMLHttp request. FormDataPreparer get the file
out of the form and prepares it for the XMLHttp request by returning
a FormData object.

Set up dummy Module call for the module Robert is building to send
url to Firebase.

TODO: deal with errors from XMLHttp request.
