Showcase the more advanced search routines in examples

[j-c-cook]

The higher level Design API is currently capable of the near-square, rectangular, bi-rectangular and bi-zoned search routines. However, Cook (2021) showcased more advanced capabilities of ghedt such as the bi-rectangular design routine with no-drilling zones (section 4.4.4 pages 143-146) and the bi-uniform polygonal constrained rectangular search with no-drilling zones (section 4.4.5, pages 146-148). While ghedt can currently perform the more advanced routines, the Design object will do much of the heavy lifting.

The purpose for this issue is to increase the functionality of the Design object to handle the even more advanced routines.
