+ * This function accepts a string containing a CSS selector,

+ *
+ * The core functionality of jQuery centers around this function.
+ * Everything in jQuery is based upon this, or uses this in some way.

+ * (usually consisting of CSS or XPath), which then finds all matching
+ * elements and remembers them for later use.
+ *
+ * By default, $() looks for DOM elements within the context of the
+ * current HTML document.

+ * @desc This finds all p elements that are children of a div element.
