class_docstr: The class used to define vectors.
  
  It along with ReferenceFrame are the building blocks of describing a
  classical mechanics system in PyDy and sympy.physics.vector.
  
  Attributes
  ==========
  
  simp : Boolean
      Let certain methods use trigsimp on their outputs

docstr: Returns a Vector which is the time derivative of
  the self Vector, taken in frame otherframe.
  
  Calls the global time_derivative method
  
  Parameters
  ==========
