Change Documentation

[irenebello]

Revising all the documentation I think this are the part we need to update:

• 4.Solution stragety: we need to add info about the libraries we are using
• 5. Building block view: we need to update this
• 6 Runtime view: when everything is working we need to add images
• 7 Deployment view: same as before, when everything is working we need to update this.
• 8 Concepts: needs and update
• 9 Design decisions: we need to put the decisions we made and the problems with the mobile app
• 10 Quality: not really sure if we need to update this or not
• 11 Technical riks: maybe is a good practice to add some of the general problems we had here, but I don´t really know
