Set defaults for checkbox_valname and checkbox_yesval to 'value' and 1 respectively, and then use summarize_vartype in hts_summary_cat and hts_summary_num to check if we're using a checkbox.
Might also requiring adding a warning about having summarize_vartype = 'checkbox' but checkbox_valname doesn't exist.
