The get_lastest_dweet() method

get_lastest_dweet() queries the dweet.io service to retrieve the latest dweet (if any) made for our thing. Following is an example of the JSON response we expect to receive. It is the content.state property on line (1) that we are ultimately interested in:

{

  by: "getting",
  the: "dweets",
  with: [
    {
      thing: "a8e38712-9886-11e9-a545-68a3c4974cd4",
      created: "2019-09-16T05:16:59.676Z",
      content: {                                               
        state: "on"                                       # (1)
      }
    }
  ]
}

Next, on line (7), the requests module...
