    Functional Description:
    Tests a pair of input keys for a 1:N relationship of discrete values within a maximum and minimun threshold for N
    Parameters:
    • InputKey: Input key for the cardinality test; this is the 1 side of the 1:N test.
    • LookupKey: Lookup key for the cardinality test; this is the N side of the 1:N test.
    • MinRelations: Minimum number of matches for a "true" result; the minimum value of N in the 1:N relationship
    • MaxRelations: Maximum number of matches for a "true" result; the maximum value of N in the 1:N relationship
    Known Limitations: None
