[Dune] svn or release version of DUNE

[Tatiana Voitovich]

Dear dune developers,

could you please let me know, on what it depends, which version --- svn or
release to use
for implementing a certain numerical scheme in DUNE+DUNE-fem. If there are
a lot of support added  in svn-version for making the development process
easier?  Would it cause problems having both versions on one computer?

I would appreciate you answer very much.

With best regards,
Tatiana
