* Improvements in Inner Outer Inner wall ordering logic
* Updated to BFS algorithm, made ordering more robust and corrected edge cases
* Doc updates
* Refinements in perimeter sorting
* Removal of touch threshold and code debugging to improve sequencing
* Code cleanup
* Code refinements on perimeter distance thresholds
* Extend perimeter re-ordering to more than inset index 2, to reduce travel moves when printing neighbouring features
* Refinements to IOI perimeter re-ordering algorithm to improve travel scenarios where multiple external perimeters are contained in the same island.
* Documentation updates
* Removed unnecessary code
* Removed bespoke to_points function and replaced with ExtrusionLine member already present. Removed squaredDistance and replaced with Eigen library call.
* Refactor code to move distancing functions to the multipoint class. Renamed for more clarity on their purpose.
