-----------------------------+-----------------------------
This patch adds set_crossed_nodes and set_node_labels methods to (non-
affine) Dynkin Diagrams and modifies the _latex_dynkin_diagram (currently
only in type A) so the data are actually used by latex.
This convenient notation is used quite often in certain subbranch of
differential geometry, see e.g. http://arxiv.org/abs/1303.1307
Moreover, there are two small bugfixes:
1. Documentation is wrong about our convention for arrows in Dynkin
diagrams.
1. Dynkin diagrams for D and E series contain a special character in the
node name of tikzpicture which TeX doesn't like.
