Display all categories on CRF even there is no count

Very often in a statistical summary table for a variable (such as race, age group), we will need to display all categories listed on the case report form even through there may be no subject falling into one of the categories.

See paper by Phillips and Klein "Oh No, a Zero Row: 5 Ways to Summarize Absolutely Nothing" for discussions of various ways in handling this.
