Слиты nikitronn запросил слияние github/fork/DolphinDream/matrixOutMK2-dev в master

Created by: DolphinDream

  • The new node now has modes that let you select the format of the output rotation component (Quaternion, Axis-Angle and Euler-Angles).
  • The node utilizes the Angle Units feature so the angle (by default set to DEGREES) can be changed to other units via Property Panel.
  • Add documentation

SV-MatrixOutMK2-AxisAngleMode SV-MatrixOutMK2-EulerAnglesMode SV-MatrixOutMK2-QuaternionMode

  • Code changes complete.
  • Code documentation complete.
  • Documentation for users complete (or not required, if user never sees these changes).
  • Manual testing done.
  • Unit-tests implemented.
  • Ready for merge.
