/*
 This view controller is based on the ALEInlineDatePickerViewController code which simplifies the presentation of a date picker inline in a tableview. This class includes a number picker as well as the date picker
 
 DATE PICKER RULES:
 The dates inserted by the user can be accessed with the corresponding date picker's indexPath.
 Must sublclass to use.
 
 Subclasses MUST do at least 2 things:
 - provide an array of indexPaths from which the date picker can be displayed (datePickerPossibleIndexPaths)
 - call super in the tableview delegate & datasource before their implementation as detailed below
 
 Notes: you can use a nib if you want and connect the tableView outlet, otherwise you can use initWithSyle:
