/**
* Extend this class when modeling a browser frame element.
*
* This class defines five constructors:
*
* - Create {@link #Frame(By, ComponentContainer) frame by locator}.
* - Create {@link #Frame(By, int, ComponentContainer) frame by locator and index}.
* - Create {@link #Frame(RobustWebElement, ComponentContainer) frame by context element}.
* - Create {@link #Frame(int, ComponentContainer) frame by index}.
* - Create {@link #Frame(String, ComponentContainer) frame by name or ID}.
*
* Your frame class can implement any of these constructors, but #3 ({@code frame by context element}) is required if
* you wish to collect multiple instances in a {@link FrameList} or {@link FrameMap}. Also note that you must override
* {@link #hashCode()} and {@link #equals(Object)} if you add significant fields.
