Instances of this class may be used to add a question mark button that when pressed, puts the
application into context-help mode. It does this by creating a ContextHelp object which itself
generates a EVT_HELP event when the user clicks on a window.
On Windows, you may add a question-mark icon to a dialog by use of the DIALOG_EX_CONTEXTHELP extra style, but
on other platforms you will have to add a button explicitly, usually next to OK, Cancel or similar buttons.
Normally you need pass only the parent window to the constructor, and use the defaults for the remaining parameters.
