class FormBuilder
Check = Struct.new(:box, :label)
# Behaves almost exactly like the select method, but instead of generating a select tag,
# generates Checks. These consist of two attributes, +box+ and +label+,
# which are (unsurprisingly) the HTML for the check box and the label. Called without a block,
# this method will return an array of check boxes. Called with a block, it will yield each
# check box to your template.
