Plugins NERDTree and NERDTree Tabs

These two plugins let you view your project's files in a sidebar similar
to Sublime or your favorite IDE.

There are two plugins here:

- NERDTree is responsible for opening up the project tree browser.
- NERDTree Tabs is responsible for opening up the same project tree
  browser on every tab.

Use \t to open or close the sidebar. For more usage information, press ?
inside the NERDTree sidebar, and read the project documentation:
