Idiom #213 Case-insensitive string compare

Compare four strings in pair-wise variations. The string comparison can be implemented with an equality test or a containment test, must be case-insensitive and must apply Unicode casefolding.

This idiom task is intended to supplant #133 which suffers from massive quality problems.
