v1.2.0

Fixed

• Corrected RAMSNAP format documentation.
• Using --continue on a finished run without averaging phases no longer throws PreconditionException
  (#68).
• Improved numerical stability of class optimize_cell.
  Before the fix, the minimal distance may have been determined incorrectly in selected cases.

Changed

• Internal error reports now show a relative path of source location instead of an absolute one.
• Documentation directory doc/ renamed to docs/ (needed for GitHub to recognize
  contributing.md).
• Distance definition is now generalized to distance vector in binning types.
• Shape functions can now be multivalued.
• Class axis shape function can now also output all three components of the axis.

Added

• Added global/local switch for class bond_order.
• Added class s220 and class s221 correlation functions.
• Added class linear binning type.
• Added class q_tensor shape function.
• Added class bin_averaged_function bulk observable.
• Added print_count switch to class pair_density_correlation, class pair_averaged_correlation,
  class density_histogram, class probability_evolution and
  class bin_averaged_function observables.
• Added normalization arguments to class density_histogram.
• Added the source code walkthrough document.
