on mu_put.php and mv_put.php we changed instantiation of Backend to support requests with certificate.
on put.php the extra newline that php was complaining about was removed.
on Backend.php was changed to adjust create series (fix algorithm that merge series),
and some bug fixes on multi SmartData insertion.
on Series.php throw exception if invalid values of t0, t1 and r was changed to include the values of these parameters.
on MultiSmartData.php: bug fix on verifying existance of ->uncertainty and adding a parseJson method.
Also, files Backend.php and SmartAPI.php were changed to support get_activity.

Reorganizing the repo structure to match the plan. Apparently, git filter-branch was not necessary to remove certificate's private key because someone had already run it. At least, git log --diff-filter=D --summary | grep delete does not show any private key.

Removing importer logs.
