Classes for creation and execution of primitives. When engine want to actully perform some action or get value of the sense, it askes some IWorkExecutor to do it.

StateWorkExecutor (used by Yaposh) takes instances of IAction and ISense and executes them. It is not very comfortable to always implement interface, so user should use one of abstract classes provided by this package:

• ParamsAction - for parametrized actions, easy to use parameters, but user has to carefuly write methods of action (reflection API is used to find methods for phases).
• StateAction - very basic abstract class implementing IAction with access to context.
• ParamsSense - for parametrized sense, easy to use parameters, but user has to carefuly write query method, the sense is using reflection API to find the method.
• StateSense - very basic abstract class implementing ISense with access to context.

Yaposh is using automatic instantiation of primitives from fully qualified names found in the plan. Automatic instantiation requires standard constructor, thus all primitives must have public constructor with one parameter - subclass of type Context (same one as in generic parameter of IAction/ISense).

All classes of primitives (the ones overriding IAction / ISense) should be annotated with PrimitiveInfo. The annotation provides useful information to the editor.
