-/**
- * Integrated Template - IT
- *
- * Well there's not much to say about it. I needed a template class that
- * supports a single template file with multiple (nested) blocks inside and
- * a simple block API.
- *
- * The Isotemplate API is somewhat tricky for a beginner although it is the best
- * one you can build. template::parse() [phplib template = Isotemplate] requests
- * you to name a source and a target where the current block gets parsed into.
- * Source and target can be block names or even handler names. This API gives you
- * a maximum of fexibility but you always have to know what you do which is
- * quite unusual for php skripter like me.
- *
- * I noticed that I do not any control on which block gets parsed into which one.
- * If all blocks are within one file, the script knows how they are nested and in
- * which way you have to parse them. IT knows that inner1 is a child of block2, there's
- * no need to tell him about this.
- *
- * <table border>
- * <tr>
- * <td colspan=2>
- * __global__
- * <p>
- * (hidden and automatically added)
- * </td>
- * </tr>
- * <tr>
- * <td>block1</td>
- * <td>
- * <table border>
- * <tr>
- * <td colspan=2>block2</td>
- * </tr>
- * <tr>
- * <td>inner1</td>
- * <td>inner2</td>
- * </tr>
- * </table>
- * </td>
- * </tr>
- * </table>
- *
- * To add content to block1 you simply type:
- * <code>$tpl->setCurrentBlock("block1");</code>
- * and repeat this as often as needed:
- * <code>
- * $tpl->setVariable(...);
- * $tpl->parseCurrentBlock();
- * </code>
- *
- * To add content to block2 you would type something like:
- * <code>
- * $tpl->setCurrentBlock("inner1");
- * $tpl->setVariable(...);
- * $tpl->parseCurrentBlock();
- *
- * $tpl->setVariable(...);
- * $tpl->parseCurrentBlock();
- *
- * $tpl->parse("block1");
- * </code>
- *
- * This will result in one repition of block1 which contains two repitions
- * of inner1. inner2 will be removed if $removeEmptyBlock is set to true which is the default.
- *
- * Usage:
- * <code>
- * $tpl = new HTML_Template_IT( [string filerootdir] );
- *
- * // load a template or set it with setTemplate()
- * $tpl->loadTemplatefile( string filename [, boolean removeUnknownVariables, boolean removeEmptyBlocks] )
- *
- * // set "global" Variables meaning variables not beeing within a (inner) block
- * $tpl->setVariable( string variablename, mixed value );
- *
- * // like with the Isotemplates there's a second way to use setVariable()
- * $tpl->setVariable( array ( string varname => mixed value ) );
- *
- * // Let's use any block, even a deeply nested one
- * $tpl->setCurrentBlock( string blockname );
- *
- * // repeat this as often as you need it.
- * $tpl->setVariable( array ( string varname => mixed value ) );
- * $tpl->parseCurrentBlock();
- *
- * // get the parsed template or print it: $tpl->show()
- * $tpl->get();
- * </code>
