Extend the ELTL parser to support basic aliases of automaton

Browse source 
operators such as F=U(true,$0) or R=!U(!$0,!$1), and infix
notation for binary automaton operators.

* README: Document the ELTL directories.
* src/eltlparse/eltlparse.yy, src/eltlparse/eltlscan.ll: Add
support for aliases and infix notation.
* src/eltlparse/public.hh, src/ltlast/nfa.cc, src/ltlast/nfa.hh:
Clean them.
* src/eltltest/acc.test, src/tgbatest/eltl2tgba.test: Add tests
for the ELTL parser's extensions.
* src/tgbatest/eltl2tgba.cc: Adjust.
