## Detailed Description

C++ "range" for iterating over the code point ranges of a USet.

using U_HEADER_NESTED_NAMESPACE::USetRanges;
LocalUSetPointer uset(uset_openPattern(u"[abcçカ🚴]", -1, &errorCode));
for (auto [start, end] : USetRanges(uset.getAlias())) {
printf("uset.range U+%04lx..U+%04lx\n", (long)start, (long)end);
}
for (auto range : USetRanges(uset.getAlias())) {
for (UChar32 c : range) {
printf("uset.range.c U+%04lx\n", (long)c);
}
}
LocalUSetPointer
"Smart pointer" class, closes a USet via uset_close().
