// This is for creating an area that users can hide and show
// It is logically made of 3 parts:
// (*) area is what gets hidden and shown
// (*) switch is the area that can be clicked for toggling
// (*) image contains a visual indication of the current status
//
// constructor needs
// (*) id: an 'id', used for naming the three parts
// (*) switch: the html text for the switch
// (*) options: a hash that can define
// - switch-tagname : to be used instead of for wrapping the switch
// - switch-bubble : might not work if switch-tagname is redefined
// - init-hidden : start hidden rather than visible
//
// methods are as follows
// (*) switch_html (): return the html code for the switch
// (*) image_html (): returns the html code for the image
// (*) area_start (): because we have too many places where php 'prints' code instead
// (*) area_end(): of returning it, we do not expect the code for the area to be passed
// so these methods can be used to delimit the area in question
