Add demo application parallel to lib

[shlomiassaf]

While developing a library it is always helpful to use an application that consumes that library within the same project.

The most obvious reasons are:

• Speeds up developments in a large factor
• Easy debugging
• Provides examples to end user
• A github.io site for presentation (script to upload can be easily integrated)

Suggested Structure:

src
---lib
---demo-app

Webpack is used for development and for bundling the output for the github.io site.
Rollup is used for NPM package creation.

demo app exists here: https://github.com/preboot/angular2-library-seed/tree/master/src
But I assume you are going for a completely separated demo app which would consume the npm lib and module.

Yep, see my repo https://github.com/shlomiassaf/angular2-modal/tree/master/src , disregard naming...

@shlomiassaf a PR sometime would be appreciated; the seed setup at the moment just mirrors https://github.com/preboot/angular2-webpack right now for ease of use and updating.
