[Feature] Hide detailed data structure from object files in debugger (can turn on/off)

[MarkChenYutian]

Is your feature request related to a problem? Please describe.

In 15-122, students are assumed to treat library provided data structures as a black box and should not learn the actual data structure used by the library. However, the C0Visualizer is not respecting this "opacity rule" in debug console.

Describe the solution you'd like

Instead of showing the actual node / expandable value for the provided data structure, show a "...hidden..." (or something similar) to the abstract data structure provided by the library.

Describe alternatives you've considered

N/A
