//** Created: March 19th, 08'
//** Aug 16th, 08'- Updated to v 1.4:
//1) Adds ability to set speed/duration of panel animation (in milliseconds)
//2) Adds persistence support, so the last viewed panel is recalled when viewer returns within same browser session
//3) Adds ability to specify whether panels should stop at the very last and first panel, or wrap around and start all over again
//4) Adds option to specify two navigational image links positioned to the left and right of the Carousel Viewer to move the panels back and forth

//** Aug 27th, 08'- Nav buttons (if enabled) also repositions themselves now if window is resized
