Adds some math/science buttons to the editor on science SE sites. These buttons are useful for converting selected text to math, formatting SI units, and formatting chemical equations.

(The SI units and chem buttons are only enabled on certain sites)

Currently, it runs on these SE sites: Mathematics, Physics, Chemistry, Biology

If you want your mathjax-enabled SE site to be supported, please let me know!

My long term goal is to make this script a part of it (I'm still working on that script, though--so it will be a while)

##Installation##

• Click here to install. Will only work in Chrome or Firefox (the latter requires Greasemonkey).
