show current corresponding shortcode block.php

// Add Shortcode
function show_current_corresponding_shortcode_block() {
/*
Used for the woocommerce product page under the Flatsome theme. Adds a shortcode that when used, looks at the current product's categories, specifically looking at a designated parent category, then going through the subcategories to see which one is marked. It assumes that marked subcategory contains the id info you'll use in a shortcode to display a certain block of content that corresponds to it. It takes the first marked subcategory, inserts the desired id info (I'm using the slug here) into the shortcode template for a block, then returns a shortcode execution function to run that shortcode with the info it found. Note, this assumes you have a bunch of blocks already created with a standardized block naming pattern that'll fit the template and match category slugs to the block shortcodes.
Args: na
Return: function invocation that executes a shortcode for a specific block (obj)
