In what order should we sort the :gen-class keys?

• alphabetical
• in the order they appear in this comment

I am leaning towards the order listed in the source comment, even though that is more complex than alphabetical.

I merged PR #33 with progress towards this. We still need to support the following :gen-class keys:

• add support for :implements
• add support for :constructors
• add support for :methods
• add support for :exposes
• add support for :exposes-methods
