untested draft for unix installation
working version of unix install script

- changed wget -> curl to avoid issue:
	https://github.com/netz98/n98-magerun/issues/75 and because curl works on more platforms
- ATLAS install not working if CPU throttling turned on, because it affects timings during algorithm tuning:
		http://math-atlas.sourceforge.net/atlas_install/node5.html
	need to adapt it to use system-wide ATLAS installation, if available
