Rendering a string of Erb/HAML back to a string (render :partial from everything else but filesystem)
# My intention is to be able to do this:
#
# from within some view, render a partial
# with the added flavour that the partial is not a file
# but rather a table model instance - like say a Customer,
# a PurchaseOrder, or in this case - a Template
# the partial rendering "should" adhere to all the standard Rails
# magic, ie nested rendering of partials, builders with Erb/HAML,
# I18n translation support to label the most important.
