Add argument for parent modifier

[roryashfordbentley]

I recently encountered a situation where I needed to add a modifier to the BEM menu <ul> but the modifier did not need to be added to children.

an example:

<ul class="main-menu  main-menu--secondary">
    <li class="main-menu__item"><a href="#">Page 1</a></li>
    <li class="main-menu__item"><a href="#">Page 2</a></li>
    <li class="main-menu__item"><a href="#">Page 3</a></li>
</ul>

I propose adding an implementation along these lines:

<?php bem_menu( 'my_menu', 'main-menu', array('main-men--secondary','main-menu--something-else') ) ?>

I think that having the last argument accept an array allows for a lot more flexibility but it keeps the code really lean.

Should the last argument accept a string as well as an array?
