/**
 * Mechanism used to locate elements within a document using a series of  lookups. This class will
 * find all DOM elements that matches any of the locators in sequence, e.g.
 *
 * <pre>
 * driver.findElements(new ByAll(by1, by2))
 * </pre>
 *
 * will find all elements that match <var>by1</var> and then all elements that match <var>by2</var>.
 * This means that the list of elements returned may not be in document order.
