The use of 'upeople' table generated by VizGrimoireR tool is being
implented, thereby we achieve to join in an only ID the contributions
done to project by the same developer with differents accounts. We can
access now to the poll with any name or email that the developer had
used in the project, since he always will be considered as the same
person. 
Also the script that generates the graphs has been modified to unify in
only one figure all contributions made by the developer with his
different accounts.
