/**
* Helper class around KoStore for writing out OASIS files.
* This class helps solving the problem that automatic styles must be before
* the body, but it's easier to iterate over the application's objects only
* once. So we open a KoXmlWriter into a memory buffer, write the body into it,
* collect automatic styles while doing that, write out automatic styles,
* and then copy the body XML from the buffer into the real KoXmlWriter.
*
* The typical use of this class is therefore:
* - write body into bodyWriter() and collect auto styles
* - write auto styles into contentWriter()
* - call closeContentWriter()
* - write other files into the store (styles.xml, settings.xml etc.)
*
*
* TODO: maybe we could encapsulate a bit more things, to e.g. handle
* adding manifest entries automatically.
