* {@link Location} is a class used by both {@link Automaton} and {@link TransitionSystem} to decribe a location.

- * A {@link Location} can be marked as initial, urgent, universal, and inconsistent.
- * In order to reduce the conversions between {@link Guard} and {@link CDD} the invariant is stored as both and only updated when required.
- * For {@link Pruning} it also stores the inconsistent part of its invariant.
+ * It is named and has coordinates describing the position where it should be drawn in the GUI.
+ * A {@link Location} can be marked as initial, urgent, universal, and inconsistent.
+ * In order to reduce the conversions between {@link Guard} and {@link CDD}
+ * the invariant is stored as both and only updated when required.
+ * For {@link Pruning} it also stores the inconsistent part of its invariant.
* <p>
- * A {@link Location} can also consist of multiple locations. If this is the case, then it is a product.
- * This is the case when combining multiple locations e.g. when performing {@link logic.Conjunction}.
- * For the product it is assumed that the order of locations also corresponds to the child {@link TransitionSystem}.
+ * A {@link Location} can also be <b>composed</b> of multiple locations (children).
+ * A composed location is created when performing {@link logic.Conjunction} for multiple systems,
+ * and it represents an n-tuple of locations correlated with the sequence of {@link TransitionSystem TransitionSystems}.
+ * For this reason the composed location are directly addressable with the index of the systems.
+ * The invariant of a composed location is lazily created as the conjunction of its children's invariants.
+ * In this context lazily created means that the locally stored invariant value in this location is only
+ * updated when a change in this composed location warrants an update to it.
+ * This can be warranted when {@link #setInvariantGuard(Guard)} is invoked.
+ * </p>
* <p>
- * A {@link Location} can also be a simple location, which is nearly the same as a product with one element.
- * The difference between a product with one element is that the simple location will always return the invariant of its child.
- * <p>
- * State overview:
+ * A {@link Location} can also be a <b>simple</b> location, which is a location with exactly one child.
+ * A simple location is used when the {@link CDD CDD invariant} of this location
+ * is not directly created from the {@link Guard Guard invariant}
+ * meaning that the {@link CDD CDD invariant} of this location will always be the {@link CDD CDD invariant} of its child,
+ * whilst the {@link Guard Guard invariant} of this location can be different from the {@link CDD CDD invariant}.
+ * This is used when performing {@link Pruning} where the {@link CDD CDD invariant} is expected to
+ * be constant whilst we are changing the {@link Guard Guard invariant}.
+ * <b>Deprecation warning:</b> <i>simple</i> locations are planned to be deprecated and one should instead create
+ * composed locations which have a more predictable specification
+ * </p>
* <ul>
+ * State overview:
* <li>name
* <li>x and y coordinates
* <li>invariant both as {@link Guard} and {@link CDD}
