aiksiongkoh 3d6a23a678 Cmake gtest (#72)
* Check rackpin and gear for zero radii

* rebase zero-radii-check (#69)

* contributing

* Update push-freecad.yml

updated actions/checkout to v4

* dragging log for debugging

* fix calcdxNorm crash

* setDebug and remove MBDyn*

* Update cmakelists.txt

* fix includes for gcc-14

gcc-14 is more disciplined about not including <algorithm> transitively.

* fix runDragStep

* backhoe files (#65)

* Mark unused variables to silence compiler warnings. (#64)

* Backhoe issues (#67)

* backhoe issues

* runDragStep edit

* backhoe issues

* runDragStep edit

* Reduce large drag step progressively until convergence.

* Switch to using built-in M_PI, even on MSVC (#68)
