title: Flask not rendering template, probably an issue with file structure
body: <p>My structure for files is this.</p>
  
  <pre><code>-App
      -services
          - __init__.py
          - app_file.py
      -templates
          - hello.html
  </code></pre>
  
  <p>Inside app_file.py, I've got </p>
  
  <pre><code>@app.route('/')
  def hello():
      return render_template('hello.html')
  </code></pre>
  
  <p>I know I have at least got a working "hello world" program, because this much worked</p>
  
  <pre><code>@app.route('/')
  def hello():
      return 'Hello World'
  </code></pre>
  
  <p>However, when I attempt the templated html, I get this error.</p>
  
  <pre><code>jinja2.exceptions.TemplateNotFound
  </code></pre>
  
  <p>As I said, I'm almost positive it is something with my file structure, so I posted only what I feel is necesary to determine if I am right or not, but will post more upon request. Help please?</p>
