Added lawnchair as a CRUD

Integrated Lawnchair as a CRUD in the PieJS framework examples of usage below. If this is of interest I can make it capable of using more than one adapter but for now its using the default DOM. If you are looking for a contributor to this project I would be more than willing to add features.

App.activeLawnChair.save('myKey', { name: 'Test' } );
App.activeLawnChair.read('myKey');
App.activeLawnChair.update('myKey', { name: 'New' });
App.activeLawnChair.destroy('myKey');
App.activeLawnChair.nuke();
App.activeLawnChair.all();
