# new implementation of balance sheet
# readme!
#
# stuff missing from the original implementation:
# - bold stuff
# - format (2 places, varying signs of negative amounts)
# - rounding (might not be necessary)
# - accno and subdescription
# - proper testing for heading charts
# - transmission from $form to TMPL realm is not as clear as i'd like
