-	 * Tests whether a value should be iterated over (e.g. in a section context).
-	 *
-	 * In most languages there are two distinct array types: list and hash (or whatever you want to call them). Lists
-	 * should be iterated, hashes should be treated as objects. Mustache follows this paradigm for Ruby, Javascript,
-	 * Java, Python, etc.
-	 *
-	 * PHP, however, treats lists and hashes as one primitive type: array. So Mustache.php needs a way to distinguish
-	 * between between a list of things (numeric, normalized array) and a set of variables to be used as section context
-	 * (associative array). In other words, this will be iterated over:
-	 *
-	 *     $items = array(
-	 *         array('name' => 'foo'),
-	 *         array('name' => 'bar'),
-	 *         array('name' => 'baz'),
-	 *     );
-	 *
-	 * ... but this will be used as a section context block:
-	 *
-	 *     $items = array(
-	 *         1        => array('name' => 'foo'),
-	 *         'banana' => array('name' => 'bar'),
-	 *         42       => array('name' => 'baz'),
-	 *     );
-	 *
-	 * @param mixed $value
-	 *
-	 * @return boolean True if the value is 'iterable'
