Redundant rotQuat.unit() call in class_Molecule_Complex.cpp

[yingyue2030699]

In class_Molecule_Complex.cpp line 1071:

      Quat rotQuat{};
      rotQuat.x = (sinX * cosY * cosZ) - (cosX * sinY * sinZ);
      rotQuat.y = (cosX * sinY * cosZ) + (sinX * cosY * sinZ);
      rotQuat.z = (cosX * cosY * sinZ) - (sinX * sinY * cosZ);
      rotQuat.w = (cosX * cosY * cosZ) + (sinX * sinY * sinZ);
      rotQuat.unit(); # <---
      const auto preparedTrajectoryRotation = rotQuat.prepareRotation();

This line produces a redundant matrix:

1. The math above for rotQuat guarantees the rotQuat to be unit quaternion within double error range.
2. rotQuat.unit() is only written as a output function, not a overwrite function so this line does nothing to begin with.
