#36 addTag() method in the DKB

[Paolo Cavalcante]

At this moment if we want to tag a model with n tags we need to call n times the WS.
We suggest to change the method:
- addTag (String sSourceUUID, String sTargetUUID, String sTag, Double value )
in:
-addTag (String sSourceUUID, String sTargetUUID, Collection<String> sTag, Double value )
in order to have the possibility to pass a list of String tags, to be able to tag a model calling the service just once.

Make also possible that everytime a user call the service all the exixting tags for that model are deleted (addTag will not add tags but it will replace tags).

Fix will be available in the next release of the DKB. New method addTag (String sSourceUUID, String sTargetUUID, Collection<String> sTag,Double value ) will be available
