Wow, the CTRL-ALT-C command to look up a function is brilliant!

Because I found Trustmaster's package so handy in every day use of Sublime Text for Cotonti, I decided to create a package for Sublime Text filled with snippets for most of Cotonti's functions.
This package allows you to easily auto-complete a function and its parameters simply by typing the function name and hitting the tab key.
It should soon be available in Package Control, but for now you can grab it manually here: https://github.com/Twiebie/cot-snippets
I'll improve the snippets over time, and any help is always appreciated!
