/**
 * ElementArrayFinder is used for operations on an array of elements (as opposed
 * to a single element).
 *
 * The ElementArrayFinder is used to set up a chain of conditions that identify
 * an array of elements. In particular, you can call all(locator) and
 * filter(filterFn) to return a new ElementArrayFinder modified by the
 * conditions, and you can call get(index) to return a single ElementFinder at
 * position 'index'.
 *
 * Similar to jquery, ElementArrayFinder will search all branches of the DOM
 * to find the elements that satisfy the conditions (i.e. all, filter, get).
 * However, an ElementArrayFinder will not actually retrieve the elements until
 * an action is called, which means it can be set up in helper files (i.e.
 * page objects) before the page is available, and reused as the page changes.
 *
 * You can treat an ElementArrayFinder as an array of WebElements for most
 * purposes, in particular, you may perform actions (i.e. click, getText) on
 * them as you would an array of WebElements. The action will apply to
 * every element identified by the ElementArrayFinder. ElementArrayFinder
 * extends Promise, and once an action is performed on an ElementArrayFinder,
 * the latest result can be accessed using then, and will be returned as an
 * array of the results; the array has length equal to the length of the
 * elements found by the ElementArrayFinder and each result represents the
 * result of performing the action on the element. Unlike a WebElement, an
 * ElementArrayFinder will wait for the angular app to settle before
 * performing finds or actions.
