My .vimrc file

I'm certainly no expert in vim or all the packages.  Here's what I have so far

vundle package manager
syntastic for syntax error flags
vim-airline for aesthetic bar and plugin integration
vim-commentary for easy comment/uncomment
vim-gitgutter to identify changes since last commit
YouCompleteMe for autocompletion (no longer bothering with it)

most of these can be installed by :PluginInstall inside vim
YouCompleteMe is a bit more indepth http://christopherpoole.github.io/setting-up-vim-with-YouCompleteMe/

vundle requires .vimrc edits to work

here is my .vimrc file
