This PR adds the
col_vals_increasing()andcol_vals_decreasing()validation methods. These validation methods checks whether column values in a table are increasing/decreasing when moving down a table. There are options for allowing for missing values in the target column, allowing stationary phases (where consecutive values don't change), and even one for allowing the opposite movement direction up to a certain threshold.
