GDSImport.ipynb:

Cell 3, Line 3: 'sub-cell'
  > To load the geometry from a GDSII file, we use `pf.load_layout`, which reads the file and returns a dictionary of `Component` objects. We then use `pf.find_top_level` to automatically identify the top-level cell — the one that is not referenced as a sub-cell by any other cell in the file:
Cell 5, Line 3: 'datatype', 'sub-cell'
  > `get_structures()` extracts all 2D structures from the component (including flattened sub-cell references), grouped by `(layer, datatype)` pairs. This tells us which layers are present and how many structures each contains:
Cell 7, Line 3: 'fabrication-related'
  > We can also define fabrication-related parameters. We consider the waveguide sidewalls to be slanted by `sidewall_angle` — positive values model the typical fabrication scenario where the base of the waveguide is wider than the top. A small `dilation` accounts for proximity effects.
Cell 8, Line 12: 'datatype'
  > # Map (layer, datatype) -> medium and extrusion parameters
