@par Protocol Description:
The Section Extraction Protocol provides a simple method of extracting
sections from arbitrarily complex files.
@param OpenSectionStream
Takes a bounded stream of sections and returns a section stream handle.
@param GetSection
Given a section stream handle, retrieves the requested section and
meta-data from the section stream.
@param CloseSectionStream
Given a section stream handle, closes the section stream.
