// This file holds some convenience methods for dealing with sessionStorage. Unlike localStorage that never expires,
// sessionStorage is cleared when the browser tab is closed since the page session ends
//
// NOTE: These storage keys are not namespaced.  That means that it's shared for the current fully
// qualified domain.  Namespacing could be added, but we'll cross that bridge when we need it.
