title: loading custom tag filters from another app
body: <p>I am really confused as to how could I load a custom tag filter from another app.
  I have a similar problem like this <a href="https://stackoverflow.com/questions/2404830/load-custom-template-tag-from-another-application">Load custom template tag from another application?</a>
  And, I am doing it the same way, but still it doesnt load up and I am getting this error :</p>
  
  <pre><code>TemplateSyntaxError at /
  'fillme_tag' is not a valid tag library: Template library fillme_tag not found, tried django.templatetags.fillme_tag,django.contrib.staticfiles.templatetags.fillme_tag,fillme.templatetags.fillme_tag
  </code></pre>
  
  <p>I have the app in settings installed app too.
  I have tried loading it using various ways as mentioned below:
  {% load fillme_tag %}
  {% load fillme.fillme_tag %} #filleme is appname.</p>
  
  <p>The structure is as follows:</p>
  
  <pre><code>my_project:
      app1:
          templates:
              index.html (this is where i want to load custom tag)
          views.py
          __init__.py
      fillme:
          templatetags:
              __init__.py
              fillme_tag.py (the tag lib)
          __init__.py
  </code></pre>
  
  <p>----- contents of fillme_tag.py ----</p>
  
  <pre><code>from django import template
  
  register = template.Library()
  
  @register.filter(name='demotag')
  def demotag(value):
      return value
  </code></pre>
