//
//  Synopsis:   Reports assertion failures to the user
//
//  Effects:
//
//  Arguments:  [pszMessage]    -- the assertion message
//              [pszFile]       -- the file it occured in
//              [uLine]         -- the line it occured at

//  Requires:

//  Returns:    void
//
//  Signals:
//
//  Modifies:
//
//  Algorithm:  Format the message and then put up a dialog box for the user.
//              They can then choose to abort the test, break to the debugger,
//              or ignore the assertion.
