* CfgBlockGenerator:

* This class describes a block generator, e.g. a function callback
* that returns a configuration snippet in a given context. Each
* user-defined "block" results in a generator to be registered, but
* theoretically this mechanism can be used to write plugins that
* generate syslog-ng configuration on the fly, based on system
* settings for example.
