/*!
@method close
@abstract Closes the receiver, unloading its web page and canceling any pending loads.
Once the receiver has closed, it will no longer respond to requests or fire delegate methods.
(However, the -close method itself may fire delegate methods.)
@discussion A garbage collected application is required to call close when the receiver is no longer needed.
The close method will be called automatically when the window or hostWindow closes and shouldCloseWithWindow returns YES.
A non-garbage collected application can still call close, providing a convenient way to prevent receiver
from doing any more loading and firing any future delegate methods.

/*!
@method setShouldCloseWithWindow:
@abstract Set whether the receiver closes when either it's window or hostWindow closes.
@param close YES if the receiver should close when either it's window or hostWindow closes, otherwise NO.
