4.1 - Where is the scriptlink API

Well it isnt here. You can edit the api files in the scriptlink/scripts/libs folder. I will probably make a good doc for it soon

1. scriptlink.py Mostly everything
2. scriptlinkbasic.py Just Utils class
3. scriptlinktk.py The tkinter gui classses
4. scriptlinknn.py Tinygrad stuff

4.2 - How do I customize the debugger

Edit scripts\libs\scriptlink.py. Its at the bottom.
