Configures the specified component appropriately for the look and feel. This method is invoked when the `ComponentUI` instance is being installed as the UI delegate on the specified component. This method should completely configure the component for the look and feel, including the following: Install default property values for color, fonts, borders, icons, opacity, etc. on the component. Whenever possible, property values initialized by the client program should not be overridden. Install a `LayoutManager` on the component if necessary. Create/add any required sub-components to the component. Create/install event listeners on the component. Create/install a `PropertyChangeListener` on the component in order to detect and respond to component property changes appropriately. Install keyboard UI (mnemonics, traversal, etc.) on the component. Initialize any appropriate instance data.

This should include the following: Remove any UI-set borders from the component. Remove any UI-set layout managers on the component. Remove any UI-added sub-components from the component. Remove any UI-added event/property listeners from the component. Remove any UI-installed keyboard UI from the component. Nullify any allocated instance data objects to allow for GC.
