Subject: [PATCH] Began system/ with client

This will contain various factories (compounded in some cases) to
instantiate various parts of a coherent system.  It aims to replace
(as one of many pieces) the ClientDependencyFactory that's referenced
in the code, which is still part of rating-fw (internal LoVullo repo
from which liza is being liberated).

* src/system/client.js: Add module.
* test/system/clientTest.js: Add functional test case.
