/**
* Returns the site header
* This loads the proper templates, does variable substitution and returns the
* HTML for the site header with or without blocks depending on the value of $what
* Programming Note:
* The two functions COM_siteHeader and COM_siteFooter provide the framework for
* page display in Geeklog. COM_siteHeader controls the display of the Header
* and left blocks and COM_siteFooter controls the dsiplay of the right blocks
* and the footer. You use them like a sandwich. Thus the following code will
* display a Geeklog page with both right and left blocks displayed.
* <code>
* <?php
* require_once 'lib-common.php';
* // Change to COM_siteHeader('none') to not display left blocks
* $display .= COM_siteHeader();
* $display .= "Here is your html for display";
* // Change to COM_siteFooter() to not display right blocks
* $display .= COM_siteFooter(true);
* echo $display;
* ? >
* </code>
* Note that the default for the header is to display the left blocks and the
* default of the footer is to not display the right blocks.
* This sandwich produces code like this (greatly simplified)
* <code>
* // COM_siteHeader
* <table><tr><td colspan="3">Header</td></tr>
* <tr><td>Left Blocks</td><td>
* // Your HTML goes here
* Here is your html for display
* // COM_siteFooter
* </td><td>Right Blocks</td></tr>
* <tr><td colspan="3">Footer</td></table>
* </code>
*
* @param string $what If 'none' then no left blocks are returned, if 'menu' (default) then right blocks are
* returned
* @param string $pagetitle optional content for the page's <title>
* @param string $headercode optional code to go into the page's <head>
