/**
 * Elementor switcher control.
 *
 * A base control for creating switcher control. Displays an on/off switcher,
 * basically a fancy UI representation of a checkbox.
 *
 * Creating new control in the editor (inside `Widget_Base::_register_controls()`
 * method):
 *
 *    $this->add_control(
 *    	'show_title',
 *    	[
 *    		'label' => __( 'Show Title', 'plugin-domain' ),
 *    		'type' => Controls_Manager::SWITCHER,
 *    		'default' => 'yes',
 *    		'return_value' => 'yes',
 *    		'label_off' => __( 'Hide', 'plugin-domain' ),
 *    		'label_on' => __( 'Show', 'plugin-domain' ),
 *    	]
 *    );
 *
 * PHP usage (inside `Widget_Base::render()` method):
 *
 *    $settings = $this->get_settings();
 *    if ( 'yes' === $settings['show_title'] ) {
 *    	echo '<h2>' . $settings['title'] . '</h2>';
 *    }
 *
 * JS usage (inside `Widget_Base::_content_template()` method):
 *
 *    <# if ( 'yes' === settings.show_title ) { #>
 *    	<h2>{{{ settings.title }}}</h2>
 *    <# } #>
