def calculateAbsoluteCoordinates(relative_coordinates, component_sequence): '''calculate the "absolute coordindates" of elements out of the "relative coordinates" The so-called "relative coordinates" are used to describe the geometrical interrelation of the elements. For example "guide2": "guide1", [0,0,3], [[1,0,0], [0,0,1], [0,-1,0]] means that guide2 is z=3 relative to guide1, and rotated 90 degrees along x axis. The format of a relative_coordinate is element: reference_element, position, orientation where position is a vector, and orientation is a 3X3 matrix. When reference_element is not specified, the entry is an absolute coordinate. There must be at least one entry in relative_coordinates that is "absolute". The whole set of relative_coordinates specification must be complete enough to resolve the absolute coordinates of all elements.
