WordPress Company Info Footer Widget - what is load_plugin_textdomain?

I have a couple questions here (I am totally new to this):

  1. What is the load_plugin_textdomain doing in the plugin?
  2. Does the register_widget go above or below the widget code?
<?php 

/*-----------------------------------------------------------------------------------*

// Creating the widget
class HAWP_PRIMARY_HCARD_Widget extends WP_Widget {
    public function __construct() {
        parent::__construct(

            // Base ID of the widget 
            'hawp_primary_hcard_widget',

            // Widget name will appear in UI
            __( 'HAWP PRIMARY HCARD Widget', 'hawpprimaryhcarddomain' ),

            // Widget description
            array(
                'classname'   => 'hawp_primary_hcard_widget',
                'description' => __( 'Add the Primary Location HCARD and NAP Schema to this widget.', 'hawpprimaryhcarddomain' )
                )
        );

    }

Hi,

Hopefully the information below will help,

1 - load_plugin_domain WordPress codec Essentially this builds a URL that tells WordPress where the multilingual files are stored, so if the plugin is available in other languages these can be loaded.

2 - Don't think this has an impact either way, but I found a good link below that covers both of these topics: WordPress Widget

So, ill give a little background before my next question. I am using a wordpress theme i bought, basically I am adding a custom widget to display schema info in the site as I dont know how to create my own custom theme yet.

So this is some code i have in a child file in the body of my site: 

<!-- Hawp Body Schema -->
<div id="<?php echo get_option($hcbodyschema); ?>" itemscope itemtype="http://schema.org/<?php echo get_option($hcbodyschema); ?>" itemref="<?php echo preg_replace('/\s+/', '-',get_option($hccity)); ?>-Location">
        <?php if(get_option($hcproductontology)) {
            echo '<link id="more-specific" itemprop="additionalType" href="http://www.productontology.org/id/'. get_option($hcproductontology) .'">';
         } ?>
<!-- /Hawp Body Schema -->

I am wanting to pull some of the options I made in the widget but it is just not displaying and im thinking its because it's not global. I want to be able to make settings in the widget for the schema and be done, not really have my own options page. So how would I pull $hcbodyschema from the theme widget in the functions.php to my header.php in the body?
