    - ENHANCEMENTS
      - Stick slope "lam" is now be use also for TIED surface-to-surface contact in 
        model_keywords.group_funcs.make_contact. If omitted, normal stiffness k is 
        used as before
      - Placement methods (move, rotate_x, ...) in CoordinateSystem now return
        "self" which enables method chaining. 
        E.g. csys.move().rotate_x().rotate(y)

    Minor bug fixes and improvements all over the place.

      - New class model_keywords.Universal to write arbitrary strings 
        to input file
      - New method model.update_mesh_from_inp(filename, ignore_unsup_elems, clear_mesh)

    - CHANGES:
      - Removed attribute "dim" from ISet.
      - Removed class ElementFace.
        Element faces inside an IElement are now represented by nested tuples
        Each face is a tuple with the node ids forming this face
        (
          (1, 2, 3), # face 1 of element, made up from nodes 1,2,3
          (1, 3, 4), # face 2 of element, made up from nodes 1,2,4
        )
      - Changes in method mesh.add_set(set_name, set_type, ids)
        If a set with given name and set_type already exists, 
        ids are added to the existing set.

        - Added Keywords *NODE PRINT, *EL PRINT, *CONTACT PRINT
        - Added result reader for frd.<br>
          With model.get_frd_results() a result object is returned for querying results from frd file
        - Added result reader for dat.<br>
          With model.get_dat_results() a result object is returned for querying results from dat file
        - Added example "specimen_weibull" as a Jupyter notebook to show
          the use of model.get_dat_results()
