// Here we have taken some SVG file from Open Clipart(http://www.openclipart.org/people/nicubunu) to

// demonstrate how to use the QML Flipable element. Think of two images. One a playing card. The

// other is simply a pattern representing back of a playing card. When the user taps on the

// Flipable element, it rotates and displays the other side of the card.

// The key point here is the transition from one state to another. We have to faces to the

// card: front and back.
