The header files are in usr/local/include but they are also in
/opt/libmesh-1.0.0-rc1/include/libmesh. I think it is because the computer
I'm using has two installations of libmesh, the libmesh-1.0.0 and
libmesh-0.7.3.2. The Libmesh-1.0.0 was only recently downloaded by my
professor/PI. I obtained the compile line by typing in:

`libmesh-config --cxx` -o foo foo.C `libmesh-config --cxxflags
--include --ldflags --libs` which I found out about from the

libmesh website section "installation".
