* %GlobalData is a container class that holds ref-count pointers to
* "global" objects, i.e., objects that nearly every LOCA object will need
* access to. By putting them all in one container class, the container
* class can be stored in each LOCA object, and if a new global object
* is needed, it can be added here without modifying the rest of the
* code. This is an alternative to true global or static objects which are
* note safe in many contexts. In particular, this approach allows multiple
* %LOCA "invocations" to be in memory at the same time. Note that all data
* members are declared public.
