//Featured Content Glider: By http://www.dynamicdrive.com



//Created: Dec 22nd, 07'



//Updated (Jan 29th, 08): Added four possible slide directions: "updown", "downup", "leftright", or "rightleft"



//Updated (Feb 1st, 08): Changed glide behavior to reverse direction when previous button is clicked



//Updated (Feb 12th, 08): Added ability to retrieve gliding contents from an external file using Ajax ("remotecontent" variable added to configuration)
