Title: a couple of fixes..

First, methods named "type" cant be called from Scala. It's a reserved word, so I've added some aliases. Ideally the old one should be depreciated/removed all together to avoid confusion. If you're ok with this, let me know and i can fix it.

The second commit is for allowing to add nodes with same name. ```addNode``` gives the impression that it adds a new node, but it really doesn't. It just replace the node with the same name with a new one. Actually, the variables are called "name" all over the place, but it *is* an id. Same thing goes for edges: you can't have multiple edges because of hashset, even tho graphviz allow it. See tests for details.
