Margins and Page Size

[Joseph D. Wagner]

I'm looking for the code in Simple API to set Margin and Page Size 
(Height and Width).

I saw the example here about getOrCreateMasterPage, but that appears to 
work only with a page break.

https://incubator.apache.org/odftoolkit/simple/document/cookbook/Text%20Document.html#Get%20TextDocument

I need to apply this to the first page of an empty doc.

Thank you for your patience and help.  I'm very new to your library.
