| Interface for classes which can dynamically load custom
plugin rules associated with a user's plugin class.
Each plugin declaration has an associated RuleLoader instance, and that
instance's addRules method is invoked each time the input xml specifies
that an instance of that plugged-in class is to be created.
This is an abstract class rather than an interface in order to make
it possible to enhance this class in future without breaking binary
compatibility; it is possible to add methods to an abstract class, but
not to an interface.
