/* This implements a sort of variable repository. One could also think of it
* as cheap version of an associative array. In each one of these
* datastructures you can store name/value pairs.
*
* All functions (should) follow the Shit-In-Shit-Out (SISO) principle, i.e.,
* you can pass them NULL pointers and the like and they will return something
* appropriate.
