Adding Custom Fields Meta Box to a page based on whether it's using a certain page template or not

This is a feature request but I would first like to start off by saying that I think your plugin is the best one out there! I had thoroughly reviewed all other such plugins before I settled with this one.

The feature request I have pertains to adding a custom fields meta box to Pages depending on whether a page uses a certain Page Template. I tried using the following by adding it to the theme's functions.php file:

This does render the form on a page with the selected page template however it doesn't save any of the fields.

I am guessing this is because the _save method of class kcSettings_post isn't aware of these fields as having been registered.
