decompose the giant NERD_tree.vim file
* Move the classes out into `plugin/nerdtree/<classname>`. * Move the other functions out into `autoload/nerdtree.vim`. Stuff still to do: * extract out at least one view class from `autoload/nerdtree` - something like NERDTreeWindow * figure out which functions in autoload/nerdtree should be scoped to the script instead of public
