/*

 * This is a simple JavaScript vertical scroller that is crossbrowser and also validates

 *

 * Usage:

 * (1) Define a <div> tag with a specified ID, containing the scrolling text. One <div> for each line.

 * (2) Define an INLINE CSS width and height (important, MUST be inline)

 * (3) Execute the divScroller function, passing id, mode (h or v),  speed (higher number means

 *     slower) and delay (in ms).
