Change Details

The Makefile copied from the old libs dir is broken by the new directory structure. It does basically three things: 1) run the tests 2) run the benchmark 3) rebuild data array files (and fetch the unicode data files for the above) 1) and 2) can be easily replaced with 'composer test' etc with appropriate config? 3) can be replaced with a nice PHP script that fetches the files and runs the build scripts, which would be less shell-dependent and may work better for third-party users. (IIRC the makefile was a little fragile and sometimes had to be tweaked to run on both OSX and Linux etc)
