*'NERDTreeWinPos'*
Values: "left", "right", "top" or "bottom"
Values: "left" or "right"
Default: "left".
This option is used to determine where NERD tree window is placed on the
screen.
"top" or "bottom", will cause a horizontal split to be created for the tree,
while "left" and "right" will cause a vertical split.
This option is makes it possible to use two different explorer type
plugins simultaneously. For example, you could have the taglist plugin on the
left of the window and the NERD tree on the right.
