577	Dynamic attribute lookup in templates	wojtek3@…	Adrian Holovaty	"I've written a tag for dynamic attribute lookup in templates.  I bet it's useful for many Django users so here it is, hopefuly it will be included in the base code :)

    Return the value of the given attribute in the given object.

    This differs from the regular use of {{ object.attribute }}.  In the case of {% get object attr_var %}
    attr_var is a variable and the actual attribute fetched from 'object' is the value of that var not
    it's name like in regular Django variable resolution.
