A Sublime Text command to take some selected text and introduce an Erlang "variable" with the selection as the assigned value. It doesn't understand the text of course, I thought you were supposed to!

Turns out my desire to share code isn't enough to get me to actually learn how to use github, so I gave up and made a new repo: https://github.com/patcorwin/ExtractAsVariable, starting from yours. I changed it so it instead puts the cursor at all locations, handling multiple selection. Thanks for the jumpstart!
