Shim code to create shared object o register Kaldi lattice with OpenFst command line tools

kaldi-arc.cc

//Compile something like (assumes the Kaldi/OpenFst headers are on the include path)
// g++ -g kaldi-arc.cc -o lattice4-arc.so \
// -shared -I/path/to/kaldi/src -DHAVE_ATLAS -fPIC
//Add the dir containing lattice4-arc.so to the LD_LIBRARY_PATH
