BSA — module DsLSRAnalysis issue

During implementation of BSA we found that some analysis can return
huge strings (not a big surprise ). Of course, the preferable way how
to deal with them is to convert the string(s) to a BioObject and use an
iterator defined for such object. However, because module DsLSRAnalysis is
designed for general usage, it should be prepared also for dealing with
long strings without any conversion (and let the client to do whatever
needed and wanted).
Therefore we are proposing to add an Iterator allowing to split long
strings into manageable pieces (and it would work on sequences of octets
as well). The remarks for such iterator:

• It does not raise any exception (such as InvalidIterator) because the
  "iterated object" is considered unmutable.
• It uses sequence of octets so it can be used for binary data as well
  (imagine transferring picture data - they may quite easily be results of
  an analysis).
• It does not have method "next()" because it does not seem to be
  necessary to ask just for one single octet.
• The parameter 'how_many' contains the maximal length of the returned
  sequence of octets in the out parameter.

Proposed resolution:
--------------------
We propose to add the following into DsLSRAnalysis module (we will
suggest what describing text to be added into the document only after we
see a concensus on this issue, but basically the text will follow comments
raised in the summary above):

interface OctetIterator
