-/**
- * Base class for all actions.
+/** Actions are Command patterns to allow for undoing and redoing.
+ *
+ * Each specific Action derives from this class to implement a certain functionality.
  *
  * Actions describe something that has to be done.
- * Actions can be passed around, stored, performed and undone (Command-Pattern).
+ * Actions can be passed around, stored, performed and undone (Command-Pattern:
+ * http://en.wikipedia.org/wiki/Command_pattern).
+ *
+ * Unique to each Action is its ActionTrait, i.e. the options it requires
+ * to perform a certain function. E.g. in order to execute a "add atom" Action
+ * we need to know a position and an element. These options have certain
+ * properties, see \ref OptionTrait and \ref ActionTrait wherein these are stored.
+ * Essentially, each option is stored as an \ref OptionTrait instance and
+ * contains the token, default value, a description, the type, ...
+ *
+ * ActionTrait itself is also an OptionTrait because the command token may actually
+ * coincide with an option-token. E.g. this allows "...--add-atom 3" to mean
+ * both execute the action under token "add-atom" and that the option "add-atom"
+ * (the new atom's \ref element number) should contain 3.
+ *
+ * \ref ActionTrait contains a map of all associated options. With this in the cstor
+ * we register not only the Action with the \ref ActionRegistry but also each of
+ * its \link options OptionTrait \endlink with the \ref OptionRegistry.
+ *
+ * The token of the option is unique, but two Action's may share the same token if:
+ * -# they have the same default value
+ * -# they have the same type
+ *
+ * This requirement is easy because if you need to store some option of another
+ * type, simply think of a new suitable name for it.
+ *
+ * The actual value, i.e. "3" in the "add-atom" example, is taken from the
+ * ValueStorage, see \ref Dialog for how this is possible.
+ *
+ * \note There is a unit test that checks on the consistency of all registered
+ * options, also in "--enable-debug"-mode assertions will check that an option
+ * has not been registered before under another type.
