Better hoisting, for faster bootstrap and less node_modules duplication

[kylecordes]

Currently this example does not use the "hoist" mode of Lerna, because Angular CLI unfortunately requires that its dependencies be installed in the immediate, local node_modules directory, rather than using standard node module resolution (which would be possible of finding "hoisted" packages).

angular/angular-cli#3864

I've already made an experimental branch which applies a bunch of symlinks to patch this up.

At some point, either ensure this is reasonably solid and use it, or hopefully see Angular CLI perform standard node resolution so that hoist "just works".

Some progress on the Angular CLI issue went in:

angular/angular-cli#6276

... but unfortunately doesn't appear to do the job fully enough yet:

angular/angular-cli#3864 (comment)

This was achieved, or made irrelevant, by switching to Nx.
