z-index too small

[joshua1]

Hi @dafcoe I am using this amazing notification library you created alongside some other vue component library . When i push notifications, it doesn't show on the screen , and I found from the rendered elements that it was hidden simply by the value of its z-index (z-40). Can this be modified , or can a class property be exposed on the component so that one can modify this value

@dafcoe , i created a pull request that exposes the z-index as a parameter
