+/**
+ * This class is called by the editor to handle spellchecking after various
+ * events. The main entrypoint is SpellCheckAfterEditorChange, which is called
+ * when the text is changed.
+ *
+ * It is VERY IMPORTANT that we do NOT do any operations that might cause DOM
+ * notifications to be flushed when we are called from the editor. This is
+ * because the call might originate from a frame, and flushing the
+ * notifications might cause that frame to be deleted.
+ *
+ * Using the WordUtil class to find words causes DOM notifications to be
+ * flushed because it asks for style information. As a result, we post an event
+ * and do all of the spellchecking in that event handler, which occurs later.
+ * We store all DOM pointers in ranges because they are kept up-to-date with
+ * DOM changes that may have happened while the event was on the queue.
+ *
+ * We also allow the spellcheck to be suspended and resumed later. This makes
+ * large pastes or initializations with a lot of text not hang the browser UI.
+ *
+ * An optimization is the mNeedsCheckAfterNavigation flag. This is set to
+ * true when we get any change, and false once there is no possibility
+ * something changed that we need to check on navigation. Navigation events
+ * tend to be a little tricky because we want to check the current word on
+ * exit if something has changed. If we navigate inside the word, we don't want
+ * to do anything. As a result, this flag is cleared in FinishNavigationEvent
+ * when we know that we are checking as a result of navigation.

+ * email addresses are treated as single words, but otherwise many kinds of
+ * punctuation are treated as word separators. GetNextWord provides a way
+ * to iterate over these "real words".
+ *
+ * The basic operation is:
+ *
+ * 1. Call Init with the weak pointer to the editor that you're using.
+ * 2. Call SetEnd to set where you want to stop spellchecking. We'll stop
+ * at the word boundary after that. If SetEnd is not called, we'll stop
+ * at the end of the document's root element.
+ * 3. Call SetPosition to initialize the current position inside the
+ * previously given range.
+ * 4. Call GetNextWord over and over until it returns false.
