# Team Tag
#
# Iterate over a list of team members, ordered by the "ordering" and "lastname" values.
#
# Syntax:
#
# {% team %}
#   {{ member.firstname }}
#   {{ member.lastname }}
#   {{ forloop }}
# {% endteam %}
#
# 'member' attributes contain all team member data (e.g., firstname, lastname, photo).
