/**
* Retrieves a value from a nested array with variable depth.
*
* This helper function should be used when the depth of the array element
* being retrieved may vary (that is, the number of parent keys is variable).
* It is primarily used for form structures and renderable arrays.
*
* Without this helper function the only way to get a nested array value with
* variable depth in one line would be using eval(), which should be avoided:
* @code
* // Do not do this! Avoid eval().
* // May also throw a PHP notice, if the variable array keys do not exist.
* eval('$value = $array[\'' . implode("']['", $parents) . "'];");
* @endcode
*
* Instead, use this helper function:
* @code
* $value = NestedArray::getValue($form, $parents);
* @endcode
*
* A return value of NULL is ambiguous, and can mean either that the requested
* key does not exist, or that the actual value is NULL. If it is required to
* know whether the nested array key actually exists, pass a third argument
* that is altered by reference:
* @code
* $key_exists = NULL;
* $value = NestedArray::getValue($form, $parents, $key_exists);
* if ($key_exists) {
* // Do something with $value.
* }
* @endcode
*
* However if the number of array parent keys is static, the value should
* always be retrieved directly rather than calling this function.
* For instance:
* @code
* $value = $form['signature_settings']['signature'];
* @endcode
* Handles on level of multiple[] values on a key.
* It will work for deeper multiples, but return the top match.
*
* @param array $array
* The array from which to get the value.
