/**
* 使用Freemarker作为模板的{@linkplain HtmlTplDashboardWidget}渲染器。
* <p>
* 此类可渲染由{@linkplain DashboardWidgetResManager}管理模板的{@linkplain HtmlTplDashboardWidget}，
* 其中{@linkplain HtmlTplDashboardWidget#getTemplate()}应该是可以通过{@linkplain DashboardWidgetResManager#getFile(String, String)}找到的模板文件名。
* </p>
* <p>
* 此类需要手动调用{@linkplain #init()}方法进行初始化。
* </p>
* <p>
* 支持的模板格式如下：
* </p>
* <code>
* <pre>
* ...
* &lt;@import /&gt;
* ...
* &lt;@theme /&gt;
* ...
* &lt;@dashboard var="..." listener="..."&gt;

* ...
* <@chart widget="..." var="..." elementId="..." /&gt;
* ...
* &lt;/@dashboard&gt;
* </pre>
* </code>
* <p>
* &lt;@import /&gt;：引入内置JS、CSS等HTML资源。
* </p>
* <p>
* &lt;@theme /&gt;：引入内置CSS主题样式。
* </p>
* <p>
* &lt;@dashboard&gt;：定义看板，“var”自定义看板JS变量名，可不填；“listener”自定义看板JS监听器，可不填。
* </p>
* <p>
* &lt;@chart
* /&gt;：定义图表，“widget”为{@linkplain HtmlChartWidget#getId()}，必填；“var”自定义图表JS变量名，可不填；“elementId”自定义图表HTML元素ID，可不填。
