Create variables useful for determining whether a row's values are suspicious
rowDistinct() finds the number of unique values given per row of variables in an array
CrunchVariable. straightlineResponse() returns a selection variable that indicates
whether the responses are identical. When a row has all columns that are missing of the
same type, it will return Selected, but will missing if any other number of values is missing
(or there are multiple types of missing).
