/**
* Allows a component to "inherit" the template (.html and .wod files) from another component.
* <p>Usage:</p>
* <pre>
* public WOElement template() {
* return inheritTemplateFrom("AddAddress", "CoreUI");
* }
* </pre>
* This very simple implementation does have some limitations:
* <ol>
* <li>It can't he used to inherit the template of another component inheriting a template.</li>
* <li>It can't handle having two components with the same name in different packages</li>
* <li>It does not use WO template caching</li>
* </ol>
*
* @see com.webobjects.appserver.WOComponent#template()
*
* @param componentName the name of the component whose template will be inherited
* @param frameworkName name of the framework the component is in, or null if in the application
* @return the template form the indicated component

Let's say I want to override the ERModernLook but I need to introduce some interfaces to it become compatible with my existing application?
