Make the attributes of the current element conveniently available in a normalized manner. Also, allow setting those attributes using the normalized names, which facilitates communication between directives and also provides a nice API for setting attributes on the DOM.
Tasks Checklist
[ ] How an element’s attribute values are made available to directives using the Attributes objects.
[ ] That boolean attribute values are always true when present on an element, but only for the standard HTML boolean attributes.
[ ] That the same Attributes object is shared by all the directives of an element.
[ ] How attributes can be $set, and how the caller can decide whether to also change the DOM or only the corresponding JavaScript property.
[ ] What the attribute name denormalization rules are when $setting an attribute on the DOM.
[ ] How attribute changes can be observed, and how that only applies to attributes set using $set and not to attributes changed by other means.
[ ] That class directives also become attributes and may optionally have values attached to them.
[ ] That comment directives also become attributes and may optionally have values attached to them.
[ ] How the Attributes object provides some convenience methods for adding, removing, and updating the CSS classes of the element.
