Lingering issues in large-example-chapter-2.ipynb:

• new name for the file? Maybe "Multistage microchip production"?
• check preamble
• code (and Pyomo model) are scattered in too many cells, probably should be consolidated in fewer?same for the markdown cells?
• code not aligned with Pyomo style guide, please refactor/rewrite it
• check data import (can it be streamlined even more?)
• missing description and intuition throughout the file? Plenty of accompanying text (it's in the book, section 2.5)
• missing full mathematical formulation of the optimization problem (it's in the book, section 2.5)
• Python/Pyomo variables should reflect those in the mathematical (e.g., x,y instead of buy, stock)
• Remove/update section title "NOTE: The functions below follow closely the naming in Overleaf"
