currency depends on 2 arrays for each currency (can be reduced)

[Ramoonus]

could also be 1 array set
making it easier to add currencies in the future / patches

[Ramoonus]

main declaration in public static $currencies

and extra in
self::$type . '_format_sign' => array( 'label' => __( 'Currency Sign', 'pods' ),

If you want to have a PR for this, I'd support it, otherwise I'll add this to the list for 3.0 stuff for me.

I'd like to see this:

    public static $currencies = array(
        'usd' => array(
            'label' => 'USD',
            'sign' => '$'
        ),
        'cad' => array(
            'label' => 'CAD',
            'sign' => '$'
        ),
        'euro' => array(
            'label' => 'Euro',
            'sign' => '€'
        ),
        'gbp' => array(
            'label' => 'GBP',
            'sign' => '£'
        )
    );

The best solution would still allow for the other filters to continue to function as they were as the backup, but utilize a new filter in __construct. So something that runs the other filters and translate them into the new array would be preferred. Also, the 'data' array in options will need building out based on the self::$currencies array too, put the 'label' in the parenthesis and have sign appear before.

No problem, I'll get to it at some point.
