Create a new Bundle "NasaBundle" within the namespace "Neo"

Create a default controller with a method helloAction
    under Nasa namespace
    for route /
    with a proper json return {"hello":"world!"}

Use the api.nasa.gov
    the API-KEY is N7LkblDsc5aen05FJqBQ8wU4qSdmsftwJagVK7UD
    documentation: https://api.nasa.gov/neo/?api_key=N7LkblDsc5aen05FJqBQ8wU4qSdmsftwJagVK7UD

Write a command
    to request the data from the last 3 days from nasa api
    response contains count of NEOs
    persist the values in your DB (mongoDB)
    Define the document as follows:
        date
        reference (neo_reference_id)
        name
        speed (kilometers_per_hour)
        is hazardous (is_potentially_hazardous_asteroid)

Create a route /neo/hazardous
    display all DB documents which contain potentially hazardous asteroids
    format JSON

Create a route /neo/fastest
    display a DB document data with the fastest asteroid
    format JSON
