Provide a playground and extensible documentation with different examples on how to customize the components.

Detect if nuxt-link or router-link are registered and allow buttons to use them.
We'll need to make the R64Button component functional

Right now we have a primary and secondary variant. We want to have a dynamic number of variants that can be defined trough the configuration theme.

We can have a variant prop that receives the variant name according to the configured theme and render the proper classes.

• Dev preview in dev.vue file with primary and secondary styles
• Storybook stories

We should add a class to our components and target them in that way.
This will allow a easier customization for the package users

Add a withoutLabelClass to apply when an input doesn't have a label.
As we are using a fixed height for inputs it actually causes having too much space below the input as there is no label on top of them.
