Deprecated headers

[Frank Dellaert]

@cforster the LieMatrix.h file itself now generates a warning :-) Find a solution? Perhaps a deprecated directory and new forwarding headers that actually generate the warning?

Also, if you run make check, the warnings are spit out for a number of files. Could you remove the #includes? Things should still work, if not create a branch/pull request and I'll see how to fix it.

How about just surrounding the include line in those three files with a #pragma to ignore that specific warning? For example, this is how we ignore an unused variable warning from including boost/bind.hpp:

#ifdef __GNUC__
#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wunused-variable"
#endif
#include <boost/bind.hpp>
#ifdef __GNUC__
#pragma GCC diagnostic pop
#endif

pragmas for every conceivable compiler? I was playing with the idea of forwarding headers anyway (to point from slam to sfm or sam), and the deprecated subdir (with a tests subdir, that is executed), makes sense to me...
