Tidy up so that both trees use the same library dependencies

It is probably the case that the -x<code> option from AX_CC_MAXOPT is sufficient to get AVX support

Updated author list, configure script to display whether libNUMA was found and install instructions. Also moved to version 0.2.0 since we have multi-timestep.

Don't see much difference in my simple tests..., LLVM support is not checked

* This is not vectorisation-specific.
* There may be better trade-offs between HT and NUMA.
* Maybe print a warning when we require multiple NUMA nodes.
* Must also detect when Hyper-Threading is not present.
* Probably better as a configure flag, rather than conditional only upon
  the availability of libnuma.
* ~15-40% performance improvement on COSMA.

This reverts commit 144739bd.

Added a simple unit test example. Test can be run using 'make check' and new tests are added by editing tests/Makefile.am

that we do not keep rebuilding library and examples.

The Makefile now generates a file containing the git revision hash key of the project. A temporary file is used for the distributed tarball versions.

The compiler modules at Durham rely on this working.
