/**

 * Plugin Name: Woocommerce Attribute Pricing
 * Description: Add the ability for administrators to affect variable product pricing by attributes.
 * Version: 0.1
 * Author: Peapod Studios
 * Author URI: http://www.peapod.ca
 *
 * Inspired by WP Ecommerce.
 *
 * Current Limitations
 * -When using the simple 'Add Variation' button, the attributes are not known when the corresponding product_variation
 * is inserted into the database.  Thus the initial attribute pricing cannot be set, and will need to be set manually.
 * A workaround would be to just always use Link All Variations.
 * -Slightly awkward is when a user sets a Base Price and then goes to Link All Variations without a Save in between.
 * The base price is not incorporated on Link All Variations.  Only on the next save is the base price incorporated.
 * Might be nice to update the base price on that text field changing
