/**
 * Register a Block Component.
 *
 * WooCommerce Blocks allows React Components to be used on the frontend of the store in place of
 * Blocks instead of just serving static content.
 *
 * Registering a Block Component allows you to define which React Component should be used in place
 * of a registered Block. The Component, when rendered, will be passed all Block Attributes.
 *
 * @param {Object}   options           Options to use when registering the block.
 * @param {Function} options.component React component that will be rendered, or the return value from  React.lazy if
 *                                     dynamically imported.
 * @param {string}   options.blockName Name of the block that this component belongs to.
 * @param {string}   [options.context] To make this component available only under a certain context
 *                                     (named parent Block) define it here. If left blank, the
 *                                     Component will be available for all contexts.
