 * This is a decorator intended to be used in conjunction with a "connected"

 * The decorator takes a function that receives state and reduces it to some
 * subset of the input. The function is invoked whenever state changes in a
 * meaningful way. This is handy for binding sub-state to LitElement properties
 * in a psuedo-declarative fashion.
