+    ## Constuct an array of hashes that will allow the user, using Liquid, to
+    ## iterate through the keys of _kv_hash_ and be able to iterate through the
+    ## elements under each key.
+    ##
+    ## Example:
+    ##   categories = { 'Ruby' => [<Post>, <Post>] }
+    ##   make_iterable(categories, :index => 'name', :items => 'posts')
+    ## Will allow the user to iterate through all categories and then iterate
+    ## though each post in the current category like so:
+    ##   {% for category in site.categories %}
+    ##     h1. {{ category.name }}
+    ##     <ul>
+    ##       {% for post in category.posts %}
+    ##         <li>{{ post.title }}</li>
+    ##       {% endfor %}
+    ##       </ul>
+    ##   {% endfor %}
+    ##
+    ## Returns [ {<index> => <kv_hash_key>, <items> => kv_hash[<kv_hash_key>]}, ... ]
