1.9-1 -> 1.10-1
===============
- added Datatypes class with lots of common regular languages 
  (was earlier placed in the dk.brics.schematools package)

- intersection now works on nondeterministic automata without determinizing
- rewritten getShortestExample
- fixed bug in subsetOf for nondeterministic automata
- removed Makefile (use 'ant' instead)

1.8-8 -> 1.9-1
==============
- moved Automaton methods to other classes (BasicAutomata, BasicOperations, etc.)
- Automaton.toString now prints singleton automata as strings without expanding them
- Automaton.subsetOf rewritten to make it faster
- Automaton.run now works on nondeterministic automata without determinizing

1.8-7 -> 1.8-8
