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.
