Worked at reviewing the DataTree code: looked at Dependencies, Interpreters, their usage in drawing operations.
Started studying the data tree visualization and the implementation of Extrude. Will continue with working at making the Extrude work with clicks, add the possibility to extrude the faces of another extrude, solve some the current bugs related to Extrude (the Extrude doesn't disable properly after choosing another tool, the Extrude drawing needs improvements, the tree list is not updated properly).
Made a list with the tasks to be implemented in the iteration that started yesterday (Iteration 0.0.10). Tomorrow, after more refining will post the tasks with their estimation.
