e4fd6a828f 1) Fixed a significant bug in MutablePriorityQueue when setting
the indices allowing rescheduling of values in the middle of the queue.
2) Implemented a cache friendly variant - MutableSkipHeapPriorityQueue
   based on

10eecb2cab Reworked Traveling Salesman Problem code for simplicity and robustness.
The TSP algorithm is newly used for planning of the printing order
of objects AND their instances.

41495a932a Introduction of a greedy Traveling Salesman Problem algorithm,
producing better shortest path estimate than the "closest next neighbor"
heuristics. The new greedy algorithm utilizes KD tree for closest
end point search, and builds a graph to detect loops.

PerimeterGenerator newly uses the optimized TSP algorithm.

ExtrusionEntity has been refactored / simplified.

0558b53493 WIP: Moved sources int src/, separated most of the source code from Perl.
The XS was left only for the unit / integration tests, and it links
libslic3r only. No wxWidgets are allowed to be used from Perl starting
from now.
