#flask/bin/python
from flask import Flask, jsonify, abort, request, make_response,url_for,render_template
from flask.ext.restful import Api, Resource
#from flask.ext.restful import restful, Api
app = Flask(__name__, static_folder ="\Flae\app\default")
api= Api(app)

@app.errorhandler(404)
def page_not_found(e):
return 'Sorry, Nothing at this URL.', 404


class Task(Resource):

    tasks = [
        {
            'id': 1,
            'message': u'You are notified'
        },
        {
            'id': 2,
