title: Python-OBD module object has no attribute "OBD"
body: <p>Having problem in bootstrapping my OBD scanner using python-obd library. I'm more of a Ruby guy, new to python. Doing the python-obd's tutorial code and terminal answers this:</p>
  
  <pre><code> File "car.py", line 2, in &lt;module&gt;
      import obd
    File "/Users/aabulkhairov/Development/publicobd/obd.py", line 3, in     &lt;module&gt;
  AttributeError: 'module' object has no attribute 'OBD'
  </code></pre>
  
  <p>Do i have to find the obd.py file and copy it to this file's folder?</p>
  
  <p>Here's the car.py:</p>
  
  <pre><code>import obd
  
  connection = obd.OBD() # auto-connects to USB or RF port
  
  cmd = obd.commands.SPEED # select an OBD command (sensor)
  
  response = connection.query(cmd) # send the command, and parse the response
  
  print(response.value) # returns unit-bearing values thanks to Pint
  print(response.value.to("mph")) # user-friendly unit conversions
  </code></pre>
