Once we've created an Elm, we can start manipulating them.
Recall from earlier that we stated that an Elm was simply an
HTMLElement that DomAPI adds some customs properties and methods
to. Let's start looking now at what some of those methods are.
This is not meant to be an exhaustive list of methods available
to Elms, but is intended merely to get you aquainted with some
of the basics. For a full list, see the documentation on
domapi.Elm(). setX( value ) Use this method to set the 'left'
attribute of the Elm, relative to its parent element. Note that
