# Carousel 1.8 [jQuery plugin for 1.3+]
#
# Copyright (C) 2010 - Snapper Net Solutions | www.snapper.no
#
# Usage:
# $('#yourcarousel').carousel()
#
#   > where #yourcarousel points to your ul containing one li per item to be displayed
#
# 1.2 adds fade as a transition mode
# 1.3 is rewritten to be more robust when used with other plugins
# 1.4 adds optional < and > (prev, next)
# 1.5 adds new mode, circle, which just circles around (slide)
# 1.6 adds new mode, noloop, as well as possibility of using custom functions for buttons/tickbox
# 1.7 adds new transition, dissolve
# 1.8 adds play() function

# Modes:
# noloop > 1, 2, 3, 4 (doesn't loop)
# restart > 1, 2, 3, 4 < 1, 2, 3, 4 (snaps rapidly back to first when finished)
# circle > 1, 2, 3, 4, 1, 2, 3, 4
