/**
 * TBehaviorParameterLoader class.
 *
 * TBehaviorParameterLoader implements attaching Behaviors from Parameters
 * before any work has been done.  Here is an example of how to attach a behavior
 * via parameter within an application.xml:
 * <code>
 * <application id="prado-app">
 *		<parameters>
 *		<parameter id="pagethemebehaviorloader" class="Prado\Util\Behaviors\TBehaviorParameterLoader" BehaviorName="testBehavior" BehaviorClass="Prado\Util\Behaviors\TParameterizeBehavior" Priority="10" AttachToClass="Prado\Web\UI\TPage" Parameter="ThemeName" Property="Theme" DefaultValue="ColoradoBlue2022" />
 *		<parameters>
 * 	  ...
 * </code>
 *
 * TBehaviorParameterLoader can be used in parameters to load behaviors through the
 * application configuration parameters, {@link TParameterModule}, as well in each
 * folder through the config.xml/php files.
 *
