   Hmm. Interesting idea, and it could be super useful, but we should think about the implementation a little bit. Maybe something like this:

   $(selector).immybox({
     choices: [
       {text: 'An ungrouped choice', value: 'something'},
       {text: 'A group', choices: [
         {text: 'A grouped choice', value: 'something_else'},
         ...
       ]}
       ...
   });

   Formally, the choices initialization option can only be an array of choices, where choice is an object with the following structure:

   {
     text: String, // required
     value: Object, // optional; if missing, choice is a "group"
     choices: Array // optional; ignored if choice is not a "group"; if choice is a "group", elements of this array must be modified_choice elements
   }

   and modified_choice is an object with the following structure:

   {
     text: String, // required
     value: Object, // required
   }

   An alternative might be to simply use the value option of choices as either the value associated with the choice (if it's not a "group"), or the choices array (if it is a "group"), and have the choice's "group" status be dictated by another option on the choice object, say is_group: Boolean.

   Yet another approach would be to use two different initialization options, e.g.:

   $(selector).immybox({
     groups: [
       {text: 'A Group', value: 'some_group'}
     ],
     choices: [
       {text: 'An ungrouped choice', value: 'something'},
       {text: 'A grouped choice', value: 'something_else', group_value: 'some_group'}
       ...
   });

   That option would be the cleanest to use, IMO, but the most difficult to implement since it would require parsing the choices into groups.

   I like the last option the most as well but it is definitely a little more involved to implement.
