Abstraction for the usual BaseAdapter "ViewHolder" pattern

BaseAdapterHelper aims to make BaseAdapter's getView() method much more readable, getting rid of the ViewHolder pattern boilerplate code.

QuickAdapter allows you to shorten the code of most usual BaseAdapter, taking care of implementing everything for you based on your data list. You only need to focus on the mapping between your view and your model.

Performance

The performances using the BaseAdapter Helper are equivalent to the ones of the ViewHolder pattern. It has been tested on thousands items list of complex item structure with more than 30 views to be adapted on each item, and the getView() method has shown similar execution times.
