Calculates how a given NSRange is affected by replacing another range with a defined length in the same context. It's a little bit like `replaceCharactersInRange:withString:` but the receiver/result is not a string but a NSRange.

UBRShiftRange

static inline NSRange UBRShiftRange(NSRange range, NSRange replacedRange, NSUInteger insertedLength) {
    
    if (replacedRange.location > range.location + range.length) {
        
        // Following
        return range;
        
    }
    
    NSRange intersection = NSIntersectionRange(range, replacedRange);
    
    if (replacedRange.location <= range.location) {
        
        // Preceding
        range.location -= (replacedRange.length - intersection.length);
        range.location += insertedLength;
        range.length -= intersection.length;
        
    } else {
        
        // Intersecting
        range.length -= intersection.length;
        range.length += insertedLength;
        
    }
    
    return range;
    
}
