Make VIM into an IDE

(1) ctags

> $sudo apt-get install exuberant-ctags

> Now go to the directory with the source files, go into it, not one level out it. And use:
    $ctags -R *

  -R indicates recursively, which means the subdirectories are also searched. And we can see a new file naned "tags".

Here are some useful cmds for ctags:

Ctrl + ]
Ctrl + t
:tag function_name 

:ta function_name
