Addresses issue #101

So I'm not even sure if this was the proper way to address the Strict errors in WP, but it seems to have worked...except for the issues outlined [on WP support](http://wordpress.org/support/topic/attempting-to-fix-the-strict-errors-in-debug-mode?replies=3#post-5078437) and [StackExchange](http://wordpress.stackexchange.com/questions/128701/working-on-fixing-wp-front-end-editor-encountering-undefined-index). The widget wrapper throws an error when turned on, and still interferes with markup when it's turend off.

Sets default values for wrap() function to quiet the strict errors when WP
is in debug mode.
