Remove the items given in the argument from the filter value.

For example:

{% print [1,2,3]|without:[2] %}

prints:

[1,3]

This filter also works on list-like values like resource edges:

{% for id in id.o.tags|without:some_id.o.tags %}

Iterates over all tags edges of the given id, for each id that is not also an edge of some_id.
