available to the Goal Manager.
An
ActionBinding is an association between a variable name and a
value.An
ActionDBEntry is the general-purpose container for one unit
of knowledge; can be factual (e.g., "person") or procedural (e.g., "goHome").ActionInterpreter is the primary step execution module for the
robot.Top level class in charge of maintaining action learning, including the current learning state
and other paused learning states (a paused learning state is different from a parent learning state),
...

of progress during action execution.

Interface for the Talos/DCEC logical proof generator
Contains the following functionality:
- Solve query via online Talos/DCEC server

- Add facts to the database through the assert asserta, assertz commands
- Remove facts from the database through the retract, retractall commands
- Prove conjecture
Features from prolog that are missing:
- Get bindings
- Probably some more stuff...

An Effect is the result of an action.

in the relevant collection

Gson can't directly populate this class because it contains a java.util.Map, so it must
be populated manually after the JSON has been parsed.

LearningComponent is the base set of methods for learning/unlearning concepts.
LearningState is used to store relevant information during learning of a new action (task or skill), including
the roles (argument and local variables), action steps, effects (success and failure), conditions (pre and operational),
also contains additional information about skills and instructions
