Summary
This PR adds the selection functionality with circle and lasso.
Left ToDo:
During selection, add the ability to switch between layers (currently not supported by nebula)
Unit tests
(Optional) I personally don't like to have multiple function that changes the class' state. Maybe the selection-model/index.ts can become a little cleaner by not having so many (a) state variables or (b) so many functions that changes the state.
