LaTex.check_tex_path has now been renamed to LaTeX.tex_path
It returns the path to your TeX binaries, or raises an exception if it can't find them.
Right now it follows a simple heuristic, by first using `which kpsewhich`, and failing that checking in /usr/texbin/ (which should work on all new MacTeX and i-installer installations) and finally /usr/local/teTeX/bin/powerpc-apple-darwin-current/, which should work on many of the older installations (though alas not the intel ones). Please suggest changes/additions to this heuristic.
