Removal of webpack in favour of rollup

Rollup offers optimizations like tree shaking that make it ideal for building shared libraries. This plugin also prioritizes defaults that are ideal for most Vue plugins and UI component libraries.

Simple Vue Lazy Load Image

• First cut of vue lazy image component to lazy load images when the target container is in the viewport.
• Added rollit so that we can prepackage our component to be used globally while importing.
• Added example to showcase lazy loading of images.
