Core data document application:  I edited the MyDocument.nib file to 
add a few fields to one view and now when I start the application, the 
main window does not appear.  Also, the new menu fails to produce a 
window.  What caused this and how do I avoid it.  More information: 
The console tells me I have a key coding problem with an NSTextView. 
I went through all the NSTextViews and made sure they were correct. 
Problem still exists.  Text from console show below.
