  The SRMonthPicker class implements an object that uses multiple rotating 
  wheels to allow users to select a month and year.  This is similar to both 
  iOS's UIDatePicker set to Date-only mode without the day element and Mobile
  Safari's picker view that appears for an `<input type="month" />` tag.

  Unlike UIDatePicker, SRMonthPicker does inherit from UIPickerView.  It does 
  use both UIPickerViewDataSource and UIPickerViewDelegate, but presents a 
  monthPickerDelegate property.
