Verna should embedded a set of standard widgets :

Form input widgets
Layout widgets

Predefined widgets

Last but not least, we also need to be able to create predefined widgets with custom properties and/or inherit from standard widgets propertiers with some value enforced.
e.g: We could image a firstname input which inherits from a text input but with following properties:
```
label: 'firstname'
help_message: string
error_message: string
required:boolean
placeholder: 'Type your firstname'
min_length: 3
max_length: 50
type: 'text'
```
