Geography tests

To test linearizations, write an input in ACE and check how the corresponding trees are multilingually linearized, i.e. put the test cases into Ace/sentences.txt.

To test parsing in languages other than ACE, e.g. of ambiguous sentences like

Der Rhein fließt durch eine Stadt die die Schweiz enthält .

put the sentences in the corresponding language directory (and possibly update the Makefile).
