OSStringsSet class abstract final

A collection of OSString with every elements comply matching staregy when the first OSString inserted.

This set not only comply single object occurence of Set, but also mandated to unify String matching method except the first added OSString element.

final strs = OSStringsSet.of(<OSString>[
  OSString.allCapital("foo"), // Retained
  OSString.caseSensitive("FOO"), // Ignored
  OSString.allCapital("bar"), // Retained
  OSString.caseSensitive("baz") // Ignored
]);
