Fix cached frame mismatch warning (issue #4)

:+1: I was running into this too, nice fix!

Here's a simplified version of the layoutAttributesForElementsInRect method, it avoids having to do multiple copies for the attributes and leverages the copied object from layoutAttributesForItemAtIndexPath.

- (NSArray *)layoutAttributesForElementsInRect:(CGRect)rect {
    NSArray *originalAttributes = [super layoutAttributesForElementsInRect:rect];
    NSMutableArray *updatedAttributes = [NSMutableArray arrayWithArray:originalAttributes];
    for (UICollectionViewLayoutAttributes *attributes in originalAttributes) {
        if (!attributes.representedElementKind) {
            NSUInteger index = [updatedAttributes indexOfObject:attributes];
            updatedAttributes[index] = [self layoutAttributesForItemAtIndexPath:attributes.indexPath];
        }
    }

    return updatedAttributes;
}
