/**
* A UniConf generator that adds a cache layer on top of another generator
*
* This cache implementation preloads the entire uniconf tree and then keeps up
* to date by making changes whenever notifications are received. This means
* that a read-only uniconfclient, when cached, will never actively contact
* the uniconfdaemon.
*
* **WARNING**
* The cache *will* go out of date if used with a uniconfclient/daemon without
* running a select loop.
