/**
* Gravity Perks // GP Read Only + GP Copy Cat // Only Disable Checkboxes Checked by GP Copy Cat
* http://gravitywiz.com/documentation/gp-read-only/
* http://gravitywiz.com/documentation/gp-copy-cat/
*
* Instructions:
*
* 1 - Copy and paste the snippet into your theme's functions.php file.
* 2 - Add the 'gw-set-checked-as-read-only' in the CSS Class Name setting for the desired field.
* 3 - Enable the Read Only setting on the Perks tab for the same field.
*
* This pairs well with GP Copy Cat where you're copying one checkbox field to another. The target field can then
* have additional checkboxes checked but the copied checkboxes are "locked". Also pairs well with GP Limit Checkboxes
* where you want to limit the total number of checkboxes that can be checked.
