The `base-datalet` is the base component that includes datalet footer (with information about dataset domain and ROUTE-TO-PA project).
Base datalet includes polymer.html and the BaseDataletBehaviors javascript file that define the datalet workcycle and the datalet base properties : dataUrl, fields and data.
Every datalet must include this one in its `<template>` section.

Example :

    <dom-module id="every-datalet">
        <template>
            ...
            <base-datalet data-url="{{dataUrl}}" fields="{{fields}}"></base-datalet>
            ...
        </template>
    </dom-module>

@element base-datalet
