" Usage:
"
" Create a project from the current nerdtree with
" :NERDTreeProjectSave <name>
"
" Load a project with
" :NERDTreeProjectLoad <name>
"
" Delete a project with
" :NERDTreeProjectRm <name>
"
" Note: <name> above will tab complete.
"
"
" Tree state (open/closed dirs) will be remembered when you return to a
" project.
