//
// Managing contexts...
// there's a lot of state associated with an "install" operation, including
// packages that are already installed, parent packages, current shrinkwrap, and
// so on. We maintain this state in a "context" object that gets passed around.
// every time we dive into a deeper node_modules folder, the "family" list that
// gets passed along uses the previous "family" list as its __proto__.  Any
// "resolved precise dependency" things that aren't already on this object get
// added, and then that's passed to the next generation of installation.
