Groups of fields with title and description

[leplatrem]

At model creation, it could be possible to define groups of fields:

SCHEMA = {
    name: "My super event",
    description: "",
    fields: [
        {   type: "string",
            name: "title",
            description: "blah",
        },
        {   name: "category",
            type: "enum",
            description: "blah",
            choices: ['sport', 'culture']
        },
        {   name: "street",
            type: "string",
        },
        {   name: "city",
            type: "string",
        },
    ],
    groups: [
        {  title: "Home",
           description:  "Your address helps us find you",
           fields: ["street", "city"]
        },
    ]
}

This would allow the UI to nicely layout the form for this model.

Since groups would be optional, they do not interfere with existing models, or those who don't need UI forms.
