Description:
 def active(parser, token):
 """ tag to determine if a link is to the current page, and if it is, sets 'link_active' to True in the context. Use: {% active path view strict[True,False] arg1 arg2 arg3 %} path: the path to check. Generally this is just 'request.path' view: the view that you want to check against the path. (uses reverse) strict: if strict is true, then the two paths need to be exactly the same. if strict is false, then a path of /some/path/ and a view with the url /some/ will match. args: args needed by the given view to get its path using reverse. Example: {% active request.path "settings" True %} <a href="{% url settings %}" class="{% if link_active %} active{% endif %}"> """
