These changes make it unnecessary to copy header files around during
the build process, which tends to confuse IDEs and debuggers. The
headers which comprise Cantera's external C++ interface are now in
the 'include' directory.
All of the samples and demos are now in the 'samples' subdirectory.
The "cantera/kernel" directory is now part of the include path only
when building the Cantera kernel. All other modules include files in
this directory as "kernel/header.h".
This fixes a problem distinguishing between kernel/Kinetics.h and
kinetics.h on Windows.
The CANTERA_DATA definition is used only in misc.cpp, so defining it
only when compiling this file reduces the amount of recompilation
required when the definition of CANTERA_DATA is changed.
This option stages "installed" files in a local directory which can
then be used to generate installation packages while $prefix still
references the final installed location.
Most f2c code needs the "f2c.h" file, which is only in the
ext/f2c_libs directory, but this error doesn't usually show up
because it is also in /usr/include on most Unix systems.
