change animation direction when the number get down or up

[nagabarc]

I try to change animation direction to up when the number decreased. i hope its useful

// exchange images & setup animation
if (mCurrentState == eFlipStateFirstHalf)

mImageViewBottom.image = [mBottomImages objectAtIndex: nextIndex];
mImageViewTop.image = [mTopImages objectAtIndex: mCurrentValue];

        // inform delegate
        if ([delegate respondsToSelector: @selector(flipNumberView:willChangeToValue:)]) {

v2 determines the direction automatically (currently on develop branch)
