What the script does
First the script creates a variable to hold the table of contents: toc.
Then it collects all <h1> and <h2> elements - in other words, level 1 and 2 headings. The
merge.context.query(selector) function searches across all Print sections (see "query
(selector)" on page957).
The query returns a result set. Each of the elements in the result set goes through the callback
function defined in each() (see "each()" on page799).
The callback function gets the element's page number, text and HTMLtag name:
var pageNo = this.info().pageNo;
var text = this.text();
var level = this.tagName();
