Addition tools for circuit design flow on colab

[anawinop]

Having more interactive tools should help design a circuit on the colab notebook.

What I have in mind are:

1. Circuit drawing (similar to what xschem does). This is usually the very first step in analog circuit design. The file format should allow import/export and is portable with spice.
2. Interactive digital circuit simulation. Having an interactive simulator would help the behavioral verification step. The tool should also produce an equivalent action script for reproducibility.

Implementation idea:
Since kernel module implementation might be challenging, utilizing widgets and html tricks (with a lot of work around) should be possible.

Please excuse me for misunderstanding if there is any.
