 /**
+ * Adds a jQuery call to the page.
+ *
+ * This is used to invoke any jQuery method on elements without having to write
+ * any associated JavaScript. Selected handlers can be bound by events (like
+ * click) or be executed on once the element is ready.
+ *
+ * @param $options
+ *   An associative array with the following keys defining the jQuery action
+ *   being added:
+ *   - selector: The jQuery selector for the element to apply the action to.
+ *   - action: (optional) The name of the jQuery function to be called. This
+ *     allows calling functions like "show", "hide", etc. If not provided,
+ *     will default to the name of the library in use, through "library".
+ *   - arguments: (optional) An array of arguments that are passed to the
+ *     element during execution.
+ *   - library: (optional) The name of the library to add, if desired. Some
+ *     examples are "ui.dialog", "effects.resizable", "ui.accordion", etc.
+ *   - module: (optional) When adding a library, this represents the name of the
+ *     module that originally registered the library. Defaults to "system".
+ *   - event: (optional) On what binded event the tool should be applied to the
+ *     element. Defaults to once the element is ready, much like the effects of
+ *     document.ready().
+ *   - bound_element: (optional) When binding on an event other than ready, will
+ *     be the element that the event is binded to. Defaults to what was passed
+ *     into the "selector" argument.
+ *   - is: (optional) Allows applying the effect only when the given condition
+ *     is met. To read more about "is", visit the jQuery documentation at:
+ *     http://docs.jquery.com/Traversing/is .
+ *   - is_selector: (optional) When acting on a conditioning attribute through
+ *     the "is" parameter, this argument represents a jQuery selector pointing
+ *     to the element that will be checked. Defaults to the "bound_element".
+ *   - return_value: (optional) The value which should be returned after the
+ *     action is taken on the bound element. Defaults to FALSE.
+ *   - actions: (optional) An array of different actions to take on the given
+ *     element. All parameters are inherited from the parent action, but can be
+ *     overriden by the chind action.
+ * @return
+ *   An array representing all elements added to the page so far.
