Variations as Single Products for WooCommerce

Out of the box, this plugin does not support multisite. We’ve got a network of shops that we’re adding this plugin to. I’ve made a modification to allow the plugin to run, but it would be great to have that modification added to the plugin so it won’t break when we update.

In the main plugin file, there is a conditional checking to see if WooCommerce is active before launching the `run_variations_as_single_products_for_woocommerce()` function. The conditional works for single sites, but not for multisites (that have WooCommerce _network_ activated).

Remove:
`if ( in_array( ‘woocommerce/woocommerce.php’, apply_filters( ‘active_plugins’, get_option( ‘active_plugins’ ) ) ) ) {`

Replace with:
`if ( class_exists( ‘woocommerce’ ) ) {`

This method comes directly from the WooCommerce documentation: https://woocommerce.com/document/query-whether-woocommerce-is-activated/
