//
//     NOTE: LyteBox was written from the Lightbox class that Lokesh Dhakar (http://www.huddletogether.com)
//			 originally wrote. The purpose was to write a self-contained object that eliminates the dependency
//			 of prototype.js, effects.js, and scriptaculous.js. Most of the core functionality and code was
//			 left in tact, and several functions were added to mimic the effects provided by sciptaculous. These
//			 newly added functions include: appear(), fade(), resizeW(), resizeH(), and toggleSelects(). Functions
//			 that were not needed were removed, as were global variables. Additionally, support has been added for
//			 iFrame environments without any code modifications needed by the end user (auto-detect).
//
//			 Other changes include:
//				- new close, next, and previous images
//				- prev/next images are always displayed (as opposed to mousing over a part of the DIV to see them)
//
//			 That being said, the original comments by Lokesh are below:
