      // Display the whole course as "weeks" made of of modules
      // Included from "view.php"
/**
 * Evaluation weekly format for course display - NO layout tables, for accessibility, etc.
 * 
 * A duplicate course format to enable the Moodle development team to evaluate 
 * CSS for the multi-column layout in place of layout tables. 
 * Less risk for the Moodle 1.6 beta release.
 *   1. Straight copy of weeks/format.php
 *   2. Replace <table> and <td> with DIVs; inline styles.
 *   3. Reorder columns so that in linear view content is first then blocks;
 * styles to maintain original graphical (side by side) view.
 *
 * Target: 3-column graphical view using relative widths for pixel screen sizes 
 * 800x600, 1024x768... on IE6, Firefox. Below 800 columns will shift downwards.
 * 
 * http://www.maxdesign.com.au/presentation/em/ Ideal length for content.
 * http://www.svendtofte.com/code/max_width_in_ie/ Max width in IE.
