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.

A whole response json can be too large to be handled as an argument to a workflow call. Thus we decided to inform the parameters with a buffer file to be read by the workflow.
Also, as previously discussed, the series workflow is not used as a filter during data querying. It is used to process the data before responding to the client.
