I've tried to pull out as much cruft and redesign to get the bare
minimum model to make it easier to use the collection_class.
What I'm trying to do:
page.template.blocks[0].elements[0]
as
page.template['content'].elements[0]
Right now, I get:
page.template.blocks[0].name = 'content'
page.template.blocks[1].name = 'menu'
so my template needs to iterate through to figure out whether I need
to walk page.template.blocks[0] or page.template.blocks[1] whereas I
would rather do:
for elements in template.blocks['content']:
Thanks.
