Packing Algorithm

Currently, the process is similar to Shelf Packing and Next Fit.

We plan to add them in the near future and make them selectable.

• Shelf Packing
• Next Fit
• Best Fit
• First Fit
• Worst Fit
• First Fit Decreasing
• Best Fit Decreasing
• Guillotine Cutting
• Skyline Algorithm
• Maximal Rectangles
