title: NameError: name 'mouse' is not defined - Python 2.7.8 & Livewires
body: <p>I am constantly getting these errors such as: 
  <code>NameError: name 'mouse' is not defined or 
  NameError: name 'screen' is not defined, etc.</code></p>
  
  <p>Here is my full error message in the Python shell: 
  <code>2.7.8 (v2.7.8:ee879c0ffa11, Jun 29 2014, 21:07:35) 
  [GCC 4.2.1 (Apple Inc. build 5666) (dot 3)]

  Traceback (most recent call last):
    File "/Volumes/PATRIOT/Our Game/ourGame.py", line 44, in &lt;module&gt;
  NameError: name 'mouse' is not defined
  </code></p>
  
  <p>I have installed Python 2.7.8 32 bit, Pygame 32 bit, and the Livewires library.  </p>
  
  <p>I've imported the Livewires library with the line:
      <code>from livewires.beginners import *</code></p>
  
  <p>Here is where I am getting errors:
      <code>mouse.is_visible = False</code></p>
  
  <p>It might be due to the fact that I did not properly install Pygame or Livewires, but when I type in the following into the Python command window I don't get errors:</p>
  
  <p><code>from livewires import beginners
  </code>
  <code>from livewires import games
  </code></p>
