/**
* This is the interface to the embeddable prompt service; the service that
* implements nsIPrompt. Its interface is designed to be just nsIPrompt, each
* method modified to take a parent window parameter.
*
* Accesskeys can be attached to buttons and checkboxes by inserting an &
* before the accesskey character in the checkbox message or button title. For
* a real &, use && instead. (A "button title" generally refers to the text
* label of a button.)
*
* One note: in all cases, the parent window parameter can be null. However,
* these windows are all intended to have parents. So when no parent is
* specified, the implementation should try hard to find a suitable foster
* parent.
*
* Implementations are free to choose how they present the various button
* types. For example, while prompts that give the user a choice between OK
* and Cancel are required to return a boolean value indicating whether or not
* the user accepted the prompt (pressed OK) or rejected the prompt (pressed
* Cancel), the implementation of this interface could very well speak the
* prompt to the user instead of rendering any visual user-interface. The
* standard button types are merely idioms used to convey the nature of the
* choice the user is to make.
*
* Because implementations of this interface may loosely interpret the various
* button types, it is advised that text messages passed to these prompts do
* not refer to the button types by name. For example, it is inadvisable to
* tell the user to "Press OK to proceed." Instead, such a prompt might be
* rewritten to ask the user: "Would you like to proceed?"
