Setting up nice emacs indentations

Add the following to the .emacs file that exists in your home directory. This should allow you to have clean indentations that are not too large or too small. Note: This will only change the indentation style for you C/C++ files not for all of emacs.

;; This should allow CXX files to format with tabs 4 spaces long
;; and allow braces to start a line without being forced to tab
;; in when you press tab.
