# The TableBuilder is a helper class that automates the creation
# of tables from collections of objects. The resulting html
# can be styled using css.
#
# === Example
#
# <?r
# users = User.all.map { |u| [u.name, u.first_name, u.last_name, u.email] }
# headers = ['Username', 'First name', 'Last name', 'Email']
# ?>
# 
# <div class="custom-table-class">
#   #{table :values => users, :headers => header}
# </div>
#--
# TODO: sorting, thead/tbody/legend etc, verbose...
