e620368696 parseaut: preliminary support for reading alternating automata 
Currently this only reads universal branches.  The parser (and the
automaton code) do not support universal initial states.

* spot/parseaut/parseaut.yy: Read universal branches.  Deal with
the no-univ-branch/!univ-branch change in HOA 1.1.
* tests/python/alternating.py: Read the output of print_hoa.
* tests/core/parseaut.test: Adjust test output, and add more tests.

6aad559c29 twa_graph: add basic support for alternation 
This only allows creating universal edges, and reading the associated
destinations.

* spot/twa/twagraph.hh (new_univ_edges, univ_dests, is_alternating): New
function.
* python/spot/impl.i: Add Python bindings.
* tests/python/alternating.py: New file.
* tests/Makefile.am: Add it.
