[Unix] Make VIM as a powerful C++ IDE

Simplly speaking, three plugin are needed:

NERE Tree: http://www.vim.org/scripts/script.php?script_id=1658

　　Show all file items in directories in the navigation sub-window in Vim.

ctags: http://www.vim.org/scripts/script.php?script_id=610

 　　Display function name in status or title bar.

taglist: http://www.vim.org/scripts/script.php?script_id=273

　　Be able to show function, classes, variable names in a sub-window for a cpp file.

I have not exprienced the effect of ctags plugin, but seems taglist also requires ctags.
