Inspect objects associated to DOM elements in web inspector.
$ component install component/dev
When enabled via localStorage.dev = true the object
is assigned as _ on the element for inspection in the
"properties" panel. This means when the element is selected
$._ is also available. A name may be passed instead of _,
however _ is nice as it will display early in the properties list.
Associate obj with el as name defaulting to "_".
