Code review for feature/labdoo_visualization

Hi Carlos @carlosb1 , when you have a chance, could you code review this branch which implements the feature 
feature/labdoo_visualization? 

It corresponds to a set of dashboards for the Labdoo objects.  I have checked it out in our development server and you can see a demo of the dashboards here: http://jordi.dev.labdoo.org/content/doojects-dashboard

Once you code review it and give me the greenlight, we can merge it to the master branch.  

Hi Dashamir @dashohoxha , i have generated some sample nodes in the above development clone (http://jordi.dev.labdoo.org/) .  Could you create a feature that stores these sample nodes for our future usage? 

Thanks.

My next action item is to work on scripts for data migration from 1.0 to 2.0.
