Optimize local node_modules to symlink to global repo

Optimizer

Idea for a small *optimize* util to speedup project creation time and keep app footprint low

var emberDevDeps = ['body-parser', 'broccoli-asset-rev', 
  'broccoli-ember-hbs-template-compiler', 'ember-cli-ember-data', 
  'ember-cli-ic-ajax', 'ember-cli-ic-ajax', 
  'ember-cli-inject-live-reload', 'ember-cli-qunit express glob'
];

$ optimize link --all

go through each module dependency in `package.json` via `npm list --depth=0`
get list of globally installed modules for those dependencies `npm list <modules referenced> --depth=0`
for each one returned, extract name and version in `Repo` object /(.*)@(.*)/
  `<name>: [<list of versions>]`

for each module dependency
  get name and version (of exact release versions only, thh like `/(\d{1,2}\.\w+)` - ignore version prefixes for now
  see if this version (exactly?) matches a globally installed module (lookup in `Repo` object)
  if so, make a symlink to global module in local /node_modules (via `npm link <module>`)
  else ignore and continue
 run `npm install` (it will ignore any local module already symlinked)

To remove symlinks, run:

$ optimize unlink

This should not conflict with the normal npm workflow with respect to updating dependencies...
But then again, perhaps too much trouble to implement all this infrastructure to circumvent a basic/standard npm mechanism. I wonder if npm 2.0 dedupe will resolve some of this
