Unique Content Cols

Key Unique Content Cols in CF Model refers to an optional 1D-array of titles that define the subset of columns specified in Sorted Columns that must contain unique data on a row-by-row basis.
Can be set by the user only when Column Choice = Custom
In other words, no two rows may exist that contain the exact same data in the columns defined here.
For technical reasons, the titles defined here must not only be a subset of the titles defined in Sorted Columns, but also be a contiguous subsequence of those titles.

If two or more rows are found that agree on their values in the columns defined here, then only the topmost of these rows is retained.
By default, the values of that retained row are kept unchanged, but it is possible to replace some of them with the numerical sum of the values that were present in the original rows.
Such columns can be specified in Sum Content Cols

If the entry described here is absent, the default is an empty array, which effectively results in a sorted table, where all rows are kept, even if they partially coincide with each other.
