dfki-ric/pytransform3d: 2.3.0

Features Serialization of TransformManager with to_dict which produces a serializable dict. An identical object can be created from a deserialized dict with from_dict. Documentation General introduction to 3D rigid transformations Update discussion of rotation matrices Bugfixes Relax numerical precision check of rotation matrices (pytransform3d.rotations.check_matrix). Instead of checking the determinant, only the components of R.dot(R.T) will be compared with I. Tests Use pytest for testing Update CI to check up to Python 3.1
