Finds variables in complex variable arrays and returns the references.

Syntax: $array_references = pvh($input_array, 'needle', EXACT_MATCH);

For example, $results = pvh($form, 'footer');
Searches through the array $form for case-insensitive text: 'footer'.

Matches are printed to the screen in PHP variable format as follows:
$form['admin']['nodes']['#options']['37']['title']->data; == admin/footer

Also returns results in a variable array so debugger can stay in session.
The search is limited to 15 tree levels to ensure proper performance.
