Modify the bingo_boxes.dat file to change possible elements in each bingo card. Each element in the .dat file should be on a new line with no comma
delimiter. The excel workbook will have each bingo card on a seperate
sheet. Maximum cards per page is 2 (default is one per page).
To modify all sheets in excel right click the first sheet and click
"Select All Sheets". Any modifications made to the first sheet should be
carried out to the remaining ones. When ready to print, be sure to select
"Entire Workbook" under the "Print what" section
