use-package allows for lazy loading C features, which means load time
is slightly smaller.

+   Setup for C and C++ modes via the cc-mode package.
+   Firstly hook the C and C++ modes to activate tabs.
+   Then set the offset to 2, and the general style to user.
+   Finally, add a user style that mimics the Microsoft guidelines for C# (open braces everywhere).
