First, thank you for the library. I appreciate the effort.
I'm working on adding support to scroll through past months also. I found an issue with scrollToDate: method while I tried to jump to a date after years.
Later, I found that happens because of you are creating monthViews initially with an offset for showing few past & future months only. When I try to jump with scrollToDate: initially, it screwed me with no view. :D
Can you look into that? Maybe we should use a better strategy to create views dynamically.
