Ordering in a line
This week I have been more oriented towards the Roassal and connecting my layouts to it. With the help of Milton (original Roassal creator) we manage to establish the connection. 
Beside this I continued with refactoring the code, by changing some names and improving the architecture of my classes, giving better descriptions and fixing some small mistakes.

I also added trait for edges, implementing empty methods in traits (methods that need to be implemented in the classes that use this train) and improve translation.

The main focus of this week at the end was adding a new type of layout, line based ones.

In some cases, just seeing our graph in a linear structure is very useful. We can implement properties based on which the size of the vertex is determiened, therefore just looking at them in a vertical or horizontal line can reveal a lot of information.
