/**
 * Like Redux actions, actions in grox are:
 *
 * 
 *   responsible for changing the state
 *   
they only produce a new state out of an old state. State being immutable.
 *   
they are pure functions, have no side effects, have no dependencies that are not pure. They
 *       are fully reproducible.
 *   
they are fully testable.
 * 
 *
 * Typically, an action is a state less object, has no dependencies and is tested.
 *
 * @param  the class of the state.
