implicitly supports a local registry and a read-only
system registry for global information.
In the context of this service,
the functions open, close, and destroy
from XSimpleRegistry are not supported and throw an exception

returns the value at the specified key in the local registry, or if
the value is not present in the local registry, it will return the value of the
system registry.
openKeys
returns a sequence of all subkeys in both registries.
getKeyNames
returns a sequence with the names of all subkeys in both registries.
Note: all write functions only work on the local registry.
How to find the registries:
search for the system registry:
The system registry will always be searched in the same directory as the
executable. The name of the system registry is "applicat.rdb". If the system
registry was not found, then the environment variable STAR_REGISTRY will be checked.
If this variable was set, it must contain a full path to a valid system registry.
Search for the user registry using the following rules:
1. (for further use) search in sversion.ini (.sversionrc) for an entry
REGISTRY_VERSION_STRING (example: UserRegistry 5.0/505=test.rdb) in the section
[Registry]. If found, then take this value instead of "user.rdb" as "REGISTRY NAME".
2. Search in the config directory of the user for a file "REGISTRY NAME". If
found, return the full path and name of the file. If not found, retry this
step with a dot before "REGISTRY NAME".
3. If not found, a new user registry with name user.rdb will be created in the user
config directory.
allows access to a registry (a persistent data source).
The data is stored in a hierarchical key structure beginning with a root key.
Each key can store a value and can have multiple subkeys.
