This is a very simple and minimal but handy service written to let you call a bootstrap modal with a template and a controller and pass some arguments to the controller.
So basically you can write:
azModal.show({
templateUrl: '/app/product/product-detail.html',
controller : 'productDetailCtrl',
locals: {product:product}
});
And a Bootstrap modal will be displayed with product
injected into decencies of productDetailCtrl
controller.
