/* The game is split into situations, which respond to user

* processing and output any content. The default implementations
* do nothing.
*
* You can either create your own type of Situation, and add
* enter, act and/or exit functions to the prototype (see
* SimpleSituation in this file for an example of that), or you
* can give those functions in the opts parameter. The opts
* parameter is an object. So you could write:
*
* var situation = Situation({
* enter: function(character, system, from) {
* ... your implementation ...
* }
* });
*
* If you pass in enter, act and/or exit through these options,
* then they should have the same function signature as the full
* function definitions, below.
*
* Note that the derived types of Situation (current
* SimpleSituation), call passed in functions AS WELL AS their
* normal action. This is most often what you want: the normal
* behavior plus a little extra custom behavior. If you want to
* override the behavior of a SimpleSituation, you'll have to
* create a derived type and set the enter, act and/or exit
* function on their prototypes. In most cases, however, if you
* want to do something completely different, it is better to

*
* extraClasses - These classes will be attached to the <div> tag
* that surrounds the quality when it is displayed. A common

* your CSS define a class for each icon, then pass those
