For example:
page has some paragraphs with text:
<p>some text1</p>
<p>some text2</p>
<p>some text3</p>
so the browser will render:
some text1
some text2
some text3
Now, if user places the Caret, lets say on text2 (between 't' and 'e' ,document is in designmode=on), the function should return ref to the second p object.
I think it should be done using range object...
