This is an internal function to determine where to separate quadrants if necessary.

quadrant_separator_find(data_table, include_total = FALSE)

## Arguments

data_table A symmetric input output table, a use table or a supply table. Should the total (intermediary) output column be included TRUE or excluded (FALSE, default)?

## Value
