+ *
+ * Supported features:

+ * Tags:
+
+<pre><code>
+ {a_variable} - output encoded.
+ {a_variable.format:("Y-m-d")} - call a method on the variable
+ {a_variable:raw} - unencoded output
+ {a_variable:toFixed(1,2)} - Roo.util.Format."toFixed"
+ {a_variable:this.method_on_template(...)} - call a method on the template object.
+
+</code></pre>
+ * The tpl tag:
+<pre><code>
+ <div roo-for="a_variable or condition.."></tpl>
+ <tpl roo-if="a_variable or condition"></tpl>
+ <tpl roo-exec="some javascript"></tpl>
+ <tpl roo-name="named_template"></tpl>
